In addition, the cost of these products has often been prohibitive for the libraries that own the print versions. Both electronic versions will incorporate future annual supplements and new print editions. It is possible to limit and sort the records using a dozen different fields, including not just author and title but also Dewey number, subject, document type, language, series title, and year of publication, although it takes a sophisticated user to accomplish some of the possible limits. All items include abridged Dewey cataloging for author, title, and subject, with links to MARC records. Where possible the records are also linked to excerpts of reviews of the books from Wilson's Book Review Digest .
Links are also available to a library's holding at no additional charge.
Records can be saved, e-mailed, and printed. One of the best searchable features available in Children's Catalog is reading level, supplied by the book's publishers. Although not all the records contain this information, it is extremely helpful to be able to identify books by topic and age level at the same time. The navigation bar is always available, with an option to view a search history and combine or refine a search. In addition, the user can open Adobe Acrobat versions of the print catalogs, allowing one to page through the Dewey classifications to identify specific subject headings.
