Those building their own book collections/libraries often ask if they can purchase Michelle's book data (on over 20,000 of the best living books on virtually every topic), so that they can precisely organize/search/share their books, and can learn of specific books to seek for their own collections. The book data is massive--including specific subjects, descriptions, series info, shelving/labeling info, etc.--on all 20,000 books, the main ones that we are all trying to rescue. The data can be used with PCs or Macs in your own data-management program. To learn more and for pricing, please contactdirectly, as this is separate from CPL. Thank you!
