In the bad old days, which ended last week, you had to go from the Library catalogue to a printed floor guide to find your books. Now every book tells you which floor of the Library it is on right beside the shelf mark number.
Maps on the central stairwell on each floor will direct you to the precise location or you can generate a custom map pointing to the exact shelving block you want using the classmark finder tool on the Library website. Before long, we hope to include these maps automatically in search results. This will finally make finding your books entirely straightforward.
If you cannot find what you are looking for, or if when you get there the bookshelf is bare, remember that Library staff are here to help you find what you need.
