Steven Cohen at LibraryStuff points us to the University of Pennsylvania's Online Books Page, and specifically to the RSS Feed for new books listed.
The Online Books Page -- completely new to me -- lists more than 20,000 full-text English-language books available around the Internet. While only the new books listing is available via RSS, the site itself lists them by author, subject, title, and LC subject heading.
