----------------------------Original message---------------------------- I pulled this message from Autocat right before ALA but do not remember seeing it on Maps-l. For those of you who catalog maps and do not subscribe to Autocat or were not at ALA I thought this message might be of interest to you. My apologies if you have seen it already.

The guidelines are intended to ensure consistent selection of the correct USMARC Type of Record (Leader/06) code by offering definitions, selection criteria, and illustrative examples. In the past, Type of Record code "m" (Computer file) was used to indicate that the content of the record was for a body of information encoded in a manner that allows it to be processed by a computer, that is, a computer file carrier (e.g., computer disk/c, computer cartridge, remote access file). MARBI Proposal No. 95-9 (Encoding of Digital Maps in the USMARC Bibliographic Format) redefined the Leader/06 code "e" from "printed map" to "cartographic material," thus making it possible to emphasize the content of the item by encoding records for cartographic materials on computer file carriers using the Leader/06 value "e" (Cartographic material), instead of "m" (Computer file). The guidelines are only intended to address issues related to the change in definition of code "e" in Leader/06 noted above. Additional guidelines will be developed and issued in the future to address the redefinition of code "m" in Leader/06 approved as part of MARBI Proposal No. 97-3R (Redefinition of code "m" (Computer file) in Leader/06 in the USMARC Bibliographic Format). The guidelines may be found at the Library of Congress Web site at http://lcweb.loc.gov/marc/cfmap.html.
