From what I've been able to read and experience with libraries so far, this doesn't seem available. If it is and someone knows how to do it, please contact me to let me know. That being said, my idea is to allow libraries to create and maintain various Sections, much like shops do with bins. This would allow literary material of a certain subject to be easily found by anyone searching, in that the listings would be broken up into things such as History, Creative, Poetry, Combat, Theology, etc as set by the Librarian. In the Ebon Fist we achieved this is sorts by having four rooms with a library in each, with each one being dedicated to a specific Shore.
