One of the requirements states that the application should show one resource at a time, and being able to browse between resources in an easy way (i'm thinking arrows), and with an option to jump directly to one resource. Right now we are showing books in a grid, and you can jump directly to a resource through this grid, which covers half of the requirement above. PR #19 adds browsing for the whole grid, but not for a single resource, and we still need to add browsing for a single resource.
