The annex is our off-site storage facility where we keep infrequently used materials.  If the item you are looking for is located in the annex, you can still obtain it easily!  Just look for the red "Recall from Annex" button at the top of the screen. 

Once recalled, the item will arrive within a day or two (you'll get an email when it does). The item can be picked up at the circulation desk.
