I noticed recently that WorldCat.org can generate an RSS feed of new books for a particular library. This feed shows you books whose records have recently been added to WorldCat.
Here’s what the feed looks like for the Newman Library. If you add that feed to a feed reader (such as the Google Reader), you can get nice updates sent to you automatically.
Just a small reminder that our loads are sent to OCLC with a 4 month delay, so the new OCLC books are in fact about 4 months old.
