Dorothea Salo has posted "The Straight Story on OAIster and Its Move" on Caveat Lector in which the University of Michigan Library's Katrina Hagedorn answers questions about the future of OAIster.
Here's an excerpt:
Q. Once oaister.org ceases to exist, there will be no way to search the harvested records for free except through worldcat.org, is that right?
A. I think those details haven’t been hammered out yet. Worldcat.org is one choice, yes. There will be likely be other products and services, and it’s likely you’ll be able to limit to just oaister records (for what that’s worth).
