There are quite a few libraries with a presence in Facebook, most of these provide simple links out of Facebook. This is quite reasonable because the overheads of programming an entire OPAC in Facebook would be huge. We’ve just added a simple link-out search to our OPAC, BIBSYS Ask.
On the other hand, it sometimes isn’t so interesting to link directly to a resource; this is exactly the case when you’re using Metalib, which can be presented in any number of ways. I’ve been testing the Facebook APIs with X-Server, and I think that the results are interesting.
This second app needs some work, but this modular design helps isolate development issues, and allows users to download only what they need (assuming perhaps that they know what they need).
