?My answer to the first question seeking a concordance of changes to atlases between editions it to a) work with the publishers or b) sit down and compare the various editions. I am not aware of any source that tracks changes between editions. My answer to the second question is to consult bibliographic records ( or even actual published items) and determine an answer to this very subjective question Ed Redmond LC, G&M ________________________________ From: Maps-L: Map Librarians, etc. <[log in to unmask]> on behalf of LOUISE RATLIFF <[log in to unmask]> Sent: Thursday, September 24, 2020 5:16 PM To: [log in to unmask] Subject: Re: Question about revisions to atlases This atlas is nice, and small.

So, for instance, country, city, national park names or their boundaries, new roads, railways...Are they updated? And secondly, he's looking for a good world atlas, smaller than a coffee table book, but he doesn't like Rand McNally (!). Any suggestions? I know these are kind of odd questions, but I told him I'd run it by the collective minds of many map librarians and see if we could get some answers. Thank you! You can respond directly to me, off-list, if you'd like!
