1990 OLAC CONFERENCE -- TECHNOLOGY: FRIEND OR FOE?
CD-ROM DISC MAINTENANCE AND CARE
Firstly, many thanks to all those of you who attended the midwinter meetings of OLAC. It never ceases to amaze that at the end of long and thing days of ALA conferencing so many of us still are able to get together and say coherent things -- or at least things that seem coherent at the time! We had much to report of interest and several pertinent cataloging issues to discuss as you can see by reading the minutes of the meetings.
The Executive Board is pleased to announce that a program of internships to CAPC is being initiated. There have been so many good volunteers to serve on CAPC the last two years that the Board would like to capitalize on this interest. Complete details of length of internship and what responsibilities are involved will hopefully firm up between now and the annual conference. We are asking two of the CAPC volunteers to accept posts as interns. The Executive Board is hoping that a system of internships will groom future members of CAPC. Internships will give opportunities for more involvement with CAPC without expanding the permanent membership.

J.O. Wallace reports for the OLAC Nominations Committee that nominations have come forward for only one person for each of the offices open for election this year. By tradition, when positions are uncontested, the nominees are appointed to the position.
I would therefore like to announce the following new officers for OLAC:
Her many activities in OLAC include serving as a member of the OLAC Conference '86 Planning Committee, 1985-86 and as the Chair of the OLAC Conference '88 Planning Committee, 1986-88. She has also been the OLAC liaison to MARBI, 1986-89 and an Ex officio member of CAPC, 1986-1989.
Ellen has served as Secretary since early 1989 when she was appointed to complete the term of Susan Gegenhuber.
Reported by Ellen Hines, Secretary
The meeting was called to order at 8:08 PM in the Gold Coast Room of the Hyatt Regency Hotel by Sharon Almquist, CAPC Chair.
Glossary
Kit. 1. An item containing two or more categories of material,
no one of which is identifiable as the
predominant constituent of the item; also designated
"multimedia item," (q.v.). 2. A single medium
package of textual material (e.g., a "lab kit," a set of
activity cards).
In order to explain the use of "lab kit", Ben Tucker walked us through the history of the term. While he and Jean Weihs were working on the first revision to AACR (mid 1970's), "lab kit" was the term used in Canada and part of the U.S. for those activity cards that have nothing but text. Since that time, "lab kit" has become increasingly obsolete and the term "activity cards" has taken its place. Ben will talk with Jean about whether "lab kit" is still a term used in Canada.
Verna noted that since activity cards are used like flash cards (which are cataloged using Chapter 8), why shouldn't they be thought of in the same way. A new GMD, "activity card", is needed to prevent these items from being split between textual and non-textual activity cards. As it now stands, textual activity cards should be cataloged under Chapter 2 (AACR2R) with the GMD "kit"; visual cards, on the other hand, are pushed into Chapter 8 with a GMD "picture." Since this is not an acceptable situation, the following is being proposed:
Kit. 1. An item containing two or more categories of material, no one of which is identifiable as the predominant constituent of the item; also designated "multimedia item" (q.v.). 2. A single-medium package of textual material (e.g., a "press kit"). c) Change footnote to:

The meeting was called to order at 8:06 PM by Verna Urbanski, OLAC Chair. After some brief welcoming remarks, Verna asked that all Board members present (Cathy Leonardi, Dorian Martyn, Cecilia Piccolo, Ellen Hines, Glenn Patton, and Sharon Almquist) and guests attending the meeting, introduce themselves.
The registration fee for the conference will be a little higher than in the past because some lunches will be included as part of that fee. Tours offered will include the Sibley Music Library, the George Eastman House (grounds and museum), and the Rochester Institute of Technology's Image Permanence Institute. Sheila also mentioned that OLAC members should make reservations directly with the Rochester Holidome in order to get conference rates (i.e., do not call the Holiday Inn 800 number). More information on all aspects of the conference will be appearing in upcoming issues of the newsletter. (Information on topics and speakers for the General Sessions and Workshops appears elsewhere in this issue. Registration information will be included in the June issue. -- Editor)
Mary also said that an attempt will be made to put together a list of programs of interest to the AV community scheduled for this summer in Chicago. If this list becomes available soon enough, it will be put in an upcoming OLAC newsletter. (This item is planned for the June issue. -- Editor)
Marilyn Craig reported that CC:DA approved the GMD "activity card" and deferred action on the related issues of the footnote (1.1C1.) and definition of "kits". Bruce Johnson and Janet Swan Hill will work together to come up with revised wording that will be presented to CC:DA this summer. CC:DA supported a position paper written by Elizabeth Stephenson that detailed how adequately Chapter 9 (Computer Files) dealt with the physical description of optical/digital media. Finally, CC:DA approved use of the GMD after the first title in collections without a collective title. Specific examples and exact wording were worked out by a task force and the accepted proposal will be going forward to the Joint Steering Committee in the fall.
Sheila Smyth began her ALCTS AV update by thanking Mary Konkel for her thorough review of the upcoming "minimal level" cataloging program (see notes above). Sheila also said that Bobbie Ferguson, current Chair of the Producer/Distributors Library Relations Subcommittee of ALCTS, would appreciate any examples of discrepancies between AV title screens, packaging & cassette itself, etc. (Sheila Smyth's ALCTS AV report appears elsewhere in this newsletter.)
Lowell Ashley reported that Jay Weitz is now the OCLC liaison to MOUG. Lowell then discussed MOUG's reaction to LC's announcement that it was considering discontinuing the coding of the 045, 047, and 048 fields for scores and musical sound recordings. Jerry McBride of Middlebury College did a survey of local practice with regard to these fields and discovered that most libraries coded these fields simply to comply with LC practice and that few indexed (or plan to index) these fields. Jerry recommended some changes in how these fields are used in order to make their use more critical. All those concerned about this issue should make their feelings known immediately to LC. The 3rd edition of the "Best of MOUG" has been published and is now available. (See order form in November MOUG newsletter, and in Lowell Ashley's MOUG report elsewhere in this issue.) MOUG will be publishing its first membership directory this year.
Ed Glazier discussed the fact that all RLIN services are now handled directly through RLG. Service hours were increased with the addition of several "search only" hours (now available Midnight PST-5:00 AM PST). A few modifications to the RLIN user interface were introduced this past fall which specifically targeted the "non-library" user (e.g., faculty). Four art museum libraries (Metropolitan Museum of Art, Museum of Modern Art, Brooklyn Museum, and Museum of Fine Arts in Boston) have been given a grant to do a major retrospective conversion project in RLIN for publications in art, architecture, and archeology. Work continues on the implementation of the Art and Architecture Thesaurus as a third authority file (target date mid-1990).
Glenn Patron encouraged all to visit the OCLC booth. He then reported that new revision pages are now available for all format documents through MARC update 1. The EPIC service (which allows reference- oriented access to the Online Union Catalog) became available on January 2, 1990. Basically, the entire MARC record is indexed and can be searched by keyword and/or phrase. Our networks should be mailing out authorization details for EPIC very soon. Another new service, GOVDOC, has just been introduced and is designed to provide automated cataloging capability for publications of the GPO (i.e., depository libraries can get card and/or tape products for all GPO publications).
Next, Glenn discussed the status of the New Online System. OCLC has signed a contract with Sprint/Telenet to begin the conversion of OCLC's current telecommunications system to today's standards. This changeover will affect local users (especially dedicated line users) when their modems need to be replaced. These conversions will be occurring gradually over a period of 15 months (beginning in fall 1990) and must be completed before a library can access the "New" System. More information about OCLC's timetable should be available in February or March 1990.
Reported by Ellen Hines, Secretary
The Board meeting was called to order at 8:03 PM by Verna Urbanski, OLAC Chair. Board members present were Catherine Leonardi, Ellen Nines, Dorian Martyn, Sharon Almquist, Glenn Patton, and Cecilia Piccolo. Guests included Bobby Ferguson, Sheila Smyth, Mary Konkel, Anne Moore, J.O. Wallace, Catherine Gerhart, and Johanne LaGrange.
The Board appointed the following people to CAPC (starting summer 1990):
Glenn Patton reported that Catherine Gerhart (University of Washington) has expressed an interest in the position of CC:DA audience observer (to fill out Marilyn Craig's term). After some discussion, Catherine was appointed to serve through 1991.
Verna said that the issue of who will replace Dick Thaxter as the LC representative to OLAC remains unresolved. She has written Jeffrey Heynen at LC about this vacancy, but has not yet received a response.
Sheila then passed out a tentative schedule for Conference activities, which was approved after minor revisions. The registration fee will be $65 (including 3 lunches) for OLAC members paying on time. Cathy Leonardi will be putting together some suggestions for non-member, late registration, etc., fees and these will be discussed later.

Reported by Sheila Smyth
The Ad Hoc Committee on 538 reviewed the US MARC Format Proposal Change Form. The change involves broadening the Technical Details Note to validate system requirements for videorecordings.
ALCTS AV Producer/Distributor-Library Relations Committee chaired by Bobby Ferguson met on Tuesday, January 9. It was reported that the variant title problems received from libraries were reviewed, attached to explanatory letters and sent to the "offending" publishers. Ten percent of these publishers responded to our letter. The committee reviewed the form and redesigned it to be format specific. Watch for examples in future OLAC Newsletters. The Committee reviewed the problems of licensing and contracts accompanying audiovisual material. Examples of these are being collected from both libraries and producer/vendors.
ALCTS AV is sponsoring a program at the ALA 1990 Annual Conference on minimal level cataloging. It will be held on Saturday, June 23, 9:30-12:30. Speakers include Steve Bregman (Nassau County Library), Gary Handman (U.C. Berkeley), Bobby Ferguson (State Library of Louisiana), Karen Homey (Northwestern U.), Glenn Patton (OCLC), and Katherine Garland (LC).
A motion to add a liaison from CCS to ALCTS AV was approved.
The meeting time for ALCTS AV was extended to include a one hour time slot on Sunday mornings from 8 to 9.
MARBI met four times during the ALA Midwinter meeting for a total of twelve and one-half hours. As I could not come until Sunday evening Bobby Ferguson attended the first two sessions and I the last two.
PROPOSED CLASSIFICATION FORMAT
The format is being developed as a standard format for communication of the data contained in various types of classification schedules. It is being developed as a generic format, one designed to be used for any type of classification. It is not being designed as an authority format. An extensive discussion on the possible uses of the format took place on Sunday. Classification numbers given in the schedules will be included, and the tables will be included, but all the possible combinations will not be specifically input.
The proposal will be rewritten and discussed much more before approval and implementation. A practical concern was expressed by the Library of Congress about the amount of staff time needed to input all the data contained in the 44 volumes of schedules (and their supplements) making up the Library of Congress Classification.
Much discussion revolved around the treatment of numbers and their captions. The earlier document put the numbers and their captions in separate fields. This document put them in separate subfields within the 153 field. That presented other problems. The amount of information making up a complete caption was also discussed, with LC captions having "as many as 17 levels of hierarchy."
Subfielding of an LC classification number was discussed at some length. In the bibliographic records, we use subfields "a" and "b." In this proposal several more subfields are used for sorting purposes. It was pointed out that a number of us with online catalogs are successfully sorting the LC classification numbers as presently subfielded, though there are problems with embedded dates and ordinal numbers such as "23rd" or "5th."
Two possible methods of treating cross-references were also discussed as were all parts of the format, from the leader and directory through the 008, 01X-04X, 6XX notes, and 7XX access and number building fields.
A proposal dealing with values for safety base film in byte 12 of the 007 was discussed.
Several proposals and discussion papers were related to concerns of the school and public library communities. Many of them are using microcomputers, and need a MARC format appropriate for microcomputer disks (a leader is not applicable to a disk).
These communities would like a specific note field in which to record awards. There was discussion as to whether an awards and exhibition field would be repeatable or would have repeatable There was also discussion of possible indicators for this information.
Also presented by this community of users was a proposal to record reading, grade, and interest level in the 521 of bibliographic records for books. This was referred back to LC for revision. There were concerns about the "labeling" of material, and whether the information should display or be used only for retrieval. This proposal will re-appear in a revised version this summer.
A discussion paper on subfielding the 538 and/or making the 753 or subfields within the 753 repeatable was tabled for reconsideration in the summer. This proposal was to provide additional access for computer files.
Another discussion paper requested that geographic names established in direct order also be added in indirect order. The discussion addressed the question of who would do a conversion of these records, how to indicate which headings were valid, and what would be done with geographic subdivision records. LC will prepare a proposal based upon the document and the discussion.
The forum participants recommended a two-tiered hierarchical approach to the handling of originals and their reproductions. The original would be handled in a bibliographic record; the reproduction in a separate holdings record. The discussions were in the content of serials and their reproductions in microform, and monographs with microform reproductions. A CC:DA task force is looking at the effect on audiovisual materials, such as films with their video reproductions. This entire concept will be addressed in greater detail this summer.
There was discussion concerning the coding of country of publication for the country of the original rather than for the reproduction, and using dates 1 and 2 for the dates of an original serial rather than for the date(s) of the reproduction. It was suggested these two concepts could be implemented soon.

Jay Weitz, OCLC Quality Control Librarian, is the new OCLC liaison to MOUG, replacing Joan Schuitema.
Last year the Library of Congress announced that it was considering discontinuing coding the 045, 047, and 048 fields in records for scores and musical sound recordings. There were a few who have expressed strong opposition to this proposal, and Jerry McBride of Middlebury College undertook a survey in the August issue of the MOUG newsletter to determine what local practices were in regard to these fields. The results were reported in the November MOUG newsletter.
Thirty-eight people responded, and the results suggested that most people were coding the fields just to follow a standard, that is, to comply with Library of Congress cataloging practice. Very few local systems were indexing these fields or were even planning to do anything with them.
In his comments about the survey, Jerry pointed out several problems with the way that these fields are currently being coded and suggested that some changes need to be made very soon which could make their potential use of sufficient value to strengthen support for continuing to code them. It seems that if nothing is done, the Library of Congress will probably discontinue the coding and the whole concept and potential usefulness of these fields is likely to be gone for all practical purposes.
Reprints of some questions and answers from the OLAC newsletter have recently appeared in the MOUG newsletter.
MOUG formed a Reference Task Force which has tested a new music-related CD-ROM product from OCLC.

The audio CD industry and its consumer market continue to endorse the compact disc as a virtually indestructible medium for audio distribution. Compared to audio tape and vinyl LP's, the CD seems to approach perfection. CD-ROM users, however, need to be more aware of the less-than-perfect nature of compact disc technology. Most crucially, both manufacturing and user-created errors are unacceptable in CD-ROM when it is used as an information distribution medium. These errors are more tolerable with audio CD's as they are often undetectable to the human ear.
Compact disc technology uses highly sophisticated error detection and correction devices that solve most manufacturing errors. CD-ROM systems are naturally more complex than audio CD systems, as the cost difference attests. CD-ROM drives are capable of recreating (not just approximating) corrupt data strings up to 4,000 bits long. These error correction devices become even more important when the retrieval software itself is stored on the CD. As we proceed to discuss CD maintenance and care, remember that most of the problems are being handled by the CD system itself. And, the better the source data, the less that is required of your system on top of correcting user-created errors.
When a CD-ROM disc arrives at your library, it becomes your responsibility to protect the disc against uncorrectable damage. A word about disc construction will help to identify potential problems. A compact disc is read from its bottom, unlabeled side. The digital code with its aluminum reflective layer, however, is directly under the top surface's protective acrylic layer and printed label. More graphically, the top 1% of the disc's entire thickness accounts for everything from the label to the digital code. The remaining 99% is made up of the polycarbonate substrate layer which gives substance to the disc. Contrary to what we might have thought, the top of a disc is therefore more vulnerable to damage than the bottom. Simply marking a disc on its top surface with normal pressure can irreparably damage a disc's data.
Data loss can also occur from damage to a disc's bottom side. Small scratches are not problematic as they are out of focus to the drive's laser lens. Larger scratches, however, can cause uncorrectable data loss, especially when they are parallel with the data tracks. A scratch perpendicular to the spiral tracks will cause fewer uncorrectable errors. For this reason, always clean your discs with a soft, dust-free cloth by gently wiping the disc from the center out to the edge. Never clean a disc with a circular motion. Avoid disc cleaning devices from audio CD stores that operate in a circular fashion. Though practiced by a leading Boston area musician, we are not ready to endorse dish washers as a suitable method of compact disc cleaning.
General recommendations for disc care include handling discs by the edges and storing discs in their jewel cases when not in use. Particularly when discs are frequently swapped, it is tempting to lay them aside unprotected. Before long they are being slid around and covered with books, manuals and other items. A half-height drive with caddy cartridges will minimize many of these problems.
Many of the newest and upcoming CD-ROM drives are including features which help to reduce the problems caused by dust build-up. Some vendors are redesigning drive doors and ventilation flow so that dust is not pulled through the disc chamber. The forthcoming Hitachi 3600/3650, for example, will also include a lens cleaning device that is automatically activated when the laser system deteriorates due to dust build-up. Laser lens cleaning devices are also available from most audio CD stores. Usually costing under $20, these cleaning discs are loaded into your drive and clean the lens with their attached brushes on the bottom side.
Each library should determine its own policies regarding the handling of its compact discs. For some libraries, the end-users may exercise proper we with the discs. In other libraries, this same practice may mean disaster. It is a wise policy to have the CD-ROM staff periodically check discs for data errors and encourage end-users to report any text or software problems.
CD-ROM technology, with all of its sophistication, is still vulnerable to simple misuse. The above recommendations are easy ways to help insure the value of your investment.
QUESTION: Our school media system purchases quite a few tape cassettes with accompanying books. The books, as separates, are entered under personal author, but is there a standard operating procedure for entering sound cassettes? According to AACR2R 21.1A2, entry should be under personal author. But when I consult 21.0B1 and 6.0B1, I become confused. Is it legitimate to enter under a personal author if the author is not named on the cassette label? Or, should all entries of this kind be under author, or under title?
ANSWER: Sound cassettes like those you mention can present an awkward situation, but we must also use common sense for part of the answer. A cassette label can be hard to work from just because it is so small and the producer is often more interested in fancy graphics to display producer/distributor information than in author information. There are a lot of variables to consider so let me just give you a few suggestions that may be helpful. I assume the recordings you refer to are spoken recordings so that corporate entry under a performing group is not an issue.
In my experience a sound cassette which accompanies a book is often "by" the same person and if cataloged separately would receive the same entry point as the book. How sound cassettes are entered should be determined from the chief source of information. If the chief source (usually the cassette and label) does not provide the information needed, take the information from a substitute chief source of information. In the case you mention this could be the "accompanying textual material," that is, the book.
If the sound cassette is intended as
accompanying material to a text [such as relaxation tapes that
accompany texts on relaxation techniques, short excerpts to illustrate the
sounds of musical instruments discussed in a text, etc.], catalog it
as accompanying material on the same catalog record and keep the two pieces
together. In many cases the content of each is enriched
by using the two together so it really does a disservice to separate the two
parts by cataloging them separately.

QUESTION: Help me with how to introduce format into the subject headings. Many librarians want to be able to call up a videocassette on sailing or a compact disc of Beethoven's symphonies. Do libraries put this under the 650 tag so it is traceable?
Examples: 650 0 $a Sailing $x Videorecordings
650 0 $a Symphonies $x Compact disc
650 0 $a Symphonies $x Sound recordings
Doing this helps our librarians quickly trace sailing video tapes or
Beethoven symphonies on CD. I would be interested to know how other
libraries handle this.
ANSWER: There is no consistent LCSH way to do this. The usage
you propose is seen on some OCLC records. It is a
nonstandard approach and would fall outside usual subject heading
maintenance routines in most libraries. I understand the problem, but would
encourage catalogers and public service personnel to work
together to select local systems that can combine media elements from the
fixed field and/or $h with subjects to gain this approach. If libraries wish
to add media names to their subject headings, they should not do so on the
permanent records they are contributing to the national databases. Though
your organization may not now maintain subject headings through online
verification systems, this could be in your future. To fully take advantage
of these automation "improvements" nonstandard subject heading use should be
kept to a
minimum .

QUESTION: In the OLAC NEWSLETTER , v.6, no.2, June 1986, there were varied answers on how to catalog a VHS hi-fi sound recording on a videocassette without pictures. Has there ever been a resolution to that issue?
My first memory of this type of recording was demonstrated at a chapter meeting of the Music Library Association, mainly to exhibit the high quality of sound one experiences in seventh generation copies, or any generation for that matter. We also were able to "watch" the digital signals of the work recorded, Igor Stravinsky's Petrouschka. The "image" on the CRT was not unlike a National Geographic Special about a Pioneer/Voyager spacecraft as it passed near Jupiter, the Red Spot, and hurricanes!! Today's digital tape has a series of barcodes as the visual, if one uses a television set for the medium of "listening/viewing." However, if one is not watching, but merely listening to the music, then a Digital Pulse Code Modulator is required. Sound recorded on the visual portion of a videocassette is said to be of higher quality if a modulator is used.
To call this a videorecording for playback purposes would be accurate, because a modulator or TV set is required. But without a note designating that this recording is only audio, the user would clearly be misled. The definition of sound recording seems to fit more, since these are "sound recordings on film (other than those intended to accompany visual images...)" (AACR2R 6.0A1). The purpose of watching a videorecording of a certain performer(s) is to learn the performer's moves, stage presence, and observe visual mannerisms. The purpose of a sound recording, whether on audiotape or videotape is to gain an understanding of the music composed, the style of the performer and musical (sound) nuances employed, to enjoy the listening experience just as one would with LP or CD recordings.
ANSWER: " ... Consider that the basic question is already
answered by Chapter 6. During the discussions 1974-1978, there were several
types of sound recordings outside the mainstream, and
even now I occasionally hear of one. For all these that we didn't
mention under 6.5B1, and for all those to come later (such as video), we put
in the provision "if none of these terms is appropriate give the specific
name of the item as concisely as possible." Because what is contained or
held by the package is a sound recording, it must be cataloged under
Chapter 5, regardless of the physical package, which is mentioned only in
the area for physical description. Using the provision I quoted, one would
quickly come up with " sound videocassette" as the specific material
designation. Some slight inventiveness is needed for the remainder of the
area, but the example of sound track film should make it clear that the
other details appropriate to the area can come from other chapters. Finally,
a note would be necessary, primarily to make it crystal clear that while the
term "videocassette" has been used in the description, don't expect any
pictures, moving images, or whatever you call the normal main component of
a videocassette. All this seems too simple to require rule additions or
interpretation -- if you accept the main point that a sound recording is a
sound recording, no matter what its physical nature.
--- Ben Tucker (LC)
After considerable thought, I believe that this is in fact the proper solution. It does pose some practical problems in transcribing information that is helpful to users of the material. Use the GMD "sound recording". The SMD that Ben suggests seems appropriate "1 sound videocassette". Since my library exercises the option to give the format note as the first note for videocassettes, I would construct a first note along the lines of:
The 007 of the sound recording format should be constructed with the videocassette format treated as "other" not as "cassette" in the subfield "b" since cassette in the 007 means specifically sound cassette. Jay Weitz at OCLC suggested the following codes for the 007:
QUESTION: I have been cataloging CD-ROM reference sources, most of which appear serially, that is, with cumulative, usually quarterly, updates. When you subscribe to, say, ERIC on Silverplatter, or AGRICOLA, you commit yourself to sending back an outdated CD-ROM each time a new one is sent to you from the vendor. Definitely a serial, right? I am finding instances on OCLC where the cataloging agency has cataloged only the archival disks, not the updates and has done them as monographs. On the MRDF format, it takes only a keystroke to change the Fixed Field Bib lvl: from m to s. Does this warrant a new record for different treatment?
ANSWER: I would probably put in a new serial record
rather than recoding a monographic record. If you input a serial record the
numerous notes that are needed to explain the life of a serial will be there
permanently so that each new user of the record
will not need to do the m to s fixed field conversion plus keying in the
needed serial notes. This treatment will be true to the nature of the item,
more efficient for the numerous libraries using the record in a national
utility, and can be essential for libraries with automated
acquisitions systems.
