You can always use the public libraries.
To create an RSS feed for new materials at your library, make a URL that starts with http://stealthislibrary.com/feed/ and finishes with keywords, separated with slashes. At least one of the keywords should be the name of the library you are searching.
Examples:http://stealthislibrary.com/feed/Multnomah/DVD
http://stealthislibrary.com/feed/San Francisco/tales
stealthislibrary.com aggregates XML from 3 web services and 3 libraries.
Bibliographic data is harvested from libraries that have the vision to provide access to XML records by accession number.
Amazon Web Services provides cover images of newly acquired materials.
Because libraries don't typically catalog materials until they have actually received them, the Library of Congress's SRU service provides additional bibliographic data we can use as access points to each record.
In the case that a book is too new to be cataloged or too old to have a cover image online, OCLC's xisbn service helps us find alternative editions of newly acquired materials.
