OK, basing myself on the idea/"Homework" of WhisakedJak for writing locations to be used by characters, here we go...
*Official name is "Secondary Depot Number 46", its nickname is "The Bookstore". Its assigned duty is to be a repository for information and equipment (and also, due to the nature of its information, can also provide rest and relaxation to personnel).
*Information has always been power, and on Coreline this information now includes stuff such as anything fictional (as a reference). The place holds many copies (both hard and digital) of books, comics (and manga), music (and audio shows), and movies (both regular entertainment pictures, episodes of shows, and training movies).
*Its cover is that of a warehouse for an online-only used bookstore, "Kane and Associates", and the false identity to which the store is registered to (a man called Roger Grant Kane) is an "eccentric comic book geek with a lot of money and some survivalist weekend warrior tendencies"
