It would be nice if the socialnetworks shown on the OPAC included GoodReads and Librarything.
I think it's time to build a system where the administrator can choose what to show in the OPAC from a list of available sharing services.
I think I might have a bug for that too :)
Neither GoodReads nor LibraryThing appear to offer a standard way for adding something from an external source. With no activity on this bug for 7 years I think this one isn't going to happen.
