In addition to Linda's suggestion about both titles in the 245, definitely put the $$b title in a 246.
Here are a few examples that may help:
Question(s) for you map catalogers out there.
We're doing a retrospective cat project to get all of our old "classic" Nat Geo maps cataloged and accessible via OPAC, etc. Many of these maps are actually "2 maps on one sheet"--e.g., a physical or thematic of some place on one side, and a political or reference map of the same place on the other.
In these cases, it's often the case that neither map is more important cartographically than the other. So to the extent that MARC necessarily (?) forces catalogers to emphasize the "main" map over all others (insets, etc.), I want to direct our cataloger to minimize the inequality of cataloging and description. To the greatest extent possible, I want/need both maps fully described and findable; I don't want one side relegated to a few words in a 500 field, for example.
Any tips on how to best accomplish this? I see records in Worldcat for some of these maps that put both titles in the 245 field, list 6xx fields that appear to cover both sides, etc. Are these legit approaches? Are there others you'd recommend?
Thanks very much for your input.
Michael
