----------------------------Original message---------------------------- Dear Colleagues, I am doing original cataloging for a map entitled "Kelleys' Map of Birmingham Alabama," published by Kelley Company, Engineers. The map folds to the size of a small booklet, with a front and back cover. The front cover has the title, " Map of Birmingham Alabama," and "published by Webb Book Company." I would like to know which publisher takes precedence for the 260 field. It seems as though the Kelley Company publishes maps--period; but the Webb Book Company went a step further and republished the map in booklet form as described above. Has anyone seen anything like this? I would appreciate any feedback on it. TIA.
