You can search OAISTER (only) again!

As of today, an OAIster only interface to more than 23 million bibliographic records is online and ready to use. You’ll find the OAIster Only interface at: http://oaister.worldcat.org/. An advanced interface is also available. You’ll also see many of the options WorldCat offers to narrow and focus a search. In essence, this is a version of WorldCat that only searches a single database of content.
