I am curious to know how other users are organizing thier libraries. How do you use tags, collections, favorites, bookmarks and layouts to organize your libraries? I haven't used tags or collections a great deal. Mostly I use layouts and favorites. For example I have a layout that I have named Easter where I placed books that deal with the cross and resurrection. I use favorites in a similar way using folders so that I can quickly view resources that are related or for resources that I want to quickly locate.
