How do you add a book to your collection

Steven, there is a good description of how to create collections on the wiki: http://wiki.logos.com/Collections

The simplest way is to drag the book from your Library to the Collections pane for that collection and drop it on + Plus these resources area. However, you might want to use tagging to form the collection or figure out a rule you can use to create a dynamic collection, which is one of the nice features of L4 collections.
