Preparing Kindles for Circulation

Although I have any number of projects that I could be working on, the library's 6 new Kindles have taken over for awhile.  There have been a surprising number of really good records in OCLC, but I'm struggling to find decent records for the Amazon Free Classics Kindle.  It has been kind of fun to do some original cataloging, though.  It's been ages since I've had a chance to do any.  North Carolina State University has some really great Kindle Book cataloging instructions on their site:  https://staff.lib.ncsu.edu/confluence/display/MNC/Kindle+E-Book+Cataloging+-+New
