If another office at Brown maintains the original document or the information will be available electronically or on microfilm or fiche for the required period of time for audit purposes , the department copy may be discarded . General disposal may be permissible for microfilm or magnetic media that have nonconfidential information but there are environmental advantages to shredding or disintegrating these media that should also be considered by agencies . The records may be maintained and preserved on microfilm or other basic source document of an automated data processing memory provided that adequate projection or viewing equipment is available , that the reproductions are clear and identifiable by date or pay period , and that extensions or transcriptions of the information required herein can be and are made available upon request . Apart from the esthetic advantages of a digital image , especially a color one , over microfilm or a photocopy , the library sees little scholarly benefit to be gained from comprehensive or even partial scanning of the most heavily used archival collections , which tend to be twentieth-century literary archives . Those who use private vendors for microfilm or computer services often store file copies of microfilm master negatives and computer back-up tapes at the vendor 's off-site location . Some library technicians operate and maintain audiovisual equipment , such as projectors , tape and CD players , and DVD and videocassette players , and assist users with microfilm or microfiche readers . Governments that use private vendors for microfilm or computer services often have microfile master copies and computer back-up tapes or disks stored at the vendor 's off-site location . It makes case processing more efficient and effective , but is far too expensive to serve solely as a replacement for microfilm or microfiche . By the same token , to open up a box of the death certificates kept by the French at the hospital in Ancon , at Panama City and to read the personal details of those who died - - their names , their age , where they came from , height , color of eyes - - was a connection with the reality of them , the mortal tale of that undertaking , that one can never find by doing the conventional kind of research with microfilm or Xeroxed copies . I am very much indebted to the many librarians , archivists , and others who responded to my queries and supplied me with microfilm or xerox copies of numerous texts . Older journal issues can be found either in bound volumes on the east side of the second floor or on microfilm or microfiche in the northeast corner of the first floor . Library catalogs typically help you locate books , journals owned by the library ( not individual articles ) , newspapers and magazines owned by the library ( not individual articles ) , documents stored on microfilm or microfiche , maps , graduate student theses and dissertations , and videotapes , audiotapes , and other multimedia items owned by the library . Integrating seamlessly with other enterprise applications and systems at the Hong Kong Immigration Department , FileNet 's ECM solution enhances overall efficiency since it enables Immigration Department staff to retrieve historical ID records instantly without having to wait for microfilm or index cards to be found and dispatched from archives . To view articles stored on microfilm or microfiche , use the equipment located by the brick wall . For the folks who point to past mistakes like microfilm-and-discard or the hasty elimination of the card catalog , I agree completely about the magnitude and tragedy of these losses - - I still remember the black , black day I walked into my local branch of the Albuquerque Public Library and found the card catalog replaced by a table full of GEAC terminals - - but the fact that people chose to destroy the original artifacts in these cases does n't mean that microfilm or online indexing themselves were bad ideas . We discard physical newspapers and magazines in the belief that nothing significant is lost when we replace them with microfilm or a digitized version .
