We're working on a tool for our library website that will allow users to save a catalog entry, a link to a journal or database, or an article citation, for future use. There are a variety of names for this kind of tool (Favorites, Saved Items, Save for Later, Bookshelf, and so on), and I'd like to learn a bit from what you've done. While many licensed databases and other web sites have this mechanism, I'm particularly interested in library-built systems.
