Delete or merge  The information is not relevant to anyone unless they are looking for information at the library in which case they would use the librarys website  If anything combine all the subpages into a single page         Having the LCC on Wikipedia is awesome I use it a lot  Wikipedia presents the LCC in a way that it can be easily studied Wikipedias version of the LCC is linkified providing instant descriptions of each topic in the LCC  So a reader can rapidly become familiar with the LCC here because Wikipedia articles are just a click away  In other presentations of the LCC the reader is left to wonder what the various categories mean  if he wants to know what a term presented in the LCC is about he or she has to look the words up and key them in somewhere else  On Wikipedia you skip that extra step  Definitely a keeper
