1. GENERAL RULE
When the work in hand is related to an edition already held by the Library, check to see that the call number of the new edition is the same as that for the edition we already have. (The new edition will, of course, have a different date in the call number.) Generally if the classification number of a later edition is changed from that of an earlier edition, we will change the earlier call number to the new class number so that all editions will sit together on the shelf. If the call numbers differ, the older edition should be pulled and the call number changed to that of the new edition. Subject headings frequently need to be changed also. The cataloger fills out a boxwork form for the older edition.
