Here is some information (in librarianese) on it form the wiki:
"bX is a service available from Ex Libris that generates recommendations for searchers. bX generates these recommendations based on actual use of link resolver services, such as SFX, using anonymized data contributed by institutions from all over the world. Recommendations can be presented in multiple interfaces including the FindIt menu and MNCAT Plus. More information about the service and how it works can be found on the Ex Libris website.
The service makes connections between articles as searchers discover and access them, so it is continually being refined and improved as more people use it and contribute their data to the system. We are still evaluating the implications of adding our own data to the larger pool, so currently we are not contributing our data. In the meantime, however, our users and staff can take full advantage of this service"

Any thoughts? Also any plans to try to simplify the Find it Menu?
