Generally, I cringe when I hear the phrase federated search, but I am excited about this project. Still, I do have some concerns, which Gary expresses succinctly:
However, even as the Google Scholar database continues to grow, we still don't know precisely when or how often it's updated, the lag time (if any) for material to get into the database, and other important facts like what will or will not be included in the database. It would also be great if Google could provide a list of sources to which they are providing access.
If you are a student or faculty and a user of Google Scholar, be sure to set your preferences so that Google Scholar is aware you are affiliated with a participating library. Then, you'll be provided with links to the full text of articles indexed by Google Scholar if your library participates in this program and your library has a paid subscription to the databases(s) that contain the articles.
