----------------------------Original message---------------------------- Hi Folks, This query concerns the use of OCLC fixed fields and type of date (Dat tp). At the Bodleian Library we have set up a working party into the possibility of automating our map catalogue, and what I wanted to find out from librarians already using OCLC fixed fields is how they deal with the case of differing dates, when the map's date of compilation differs from its publication date. Is code "r" used, or have any libraries found a more appropriate means of answering this dilemma? Thanks in advance for your replies.
