Bruner Project
Scanning Standards
(Archival and Display)

Spring 2000


The scanner settings used are determined by the type of document in hand. In the Bruner project there are 4 document types:

  1. Text: perspective sheets, articles, background information, etc.
  2. Drawings, Maps, Illustrations, etc.: These include, siteplans, blueprints, archtect renderings, etc.
  3. Photographs: Black and white and color.
  4. Graphics: logos, PR material, advertisements, etc.


For each of these documents and archival "master file" is created. These large, high-resolution TIF files are created in order to retain as much data as possible from the original document scan. Smaller files (GIF, JPEG) are then derived from the master a nd used for screen display. Because these derivative files are compressed, they will load much faster and use up significantly less file space than their archival TIF counterparts.

  • Standards information derived from NARA Guidelines for Digitizing Archival Materials for Electronic Access, compiled by Steven Puglia, National Archives and Records Administration, 1998.

    Oversized Images
    If an image is larger than legal size, it must be scanned in pieces. Follow the same resolution standards outlined above, taking into consideration the size of the "whole" document. Photoshop will be used to "reassemble" the document.
