Slowly chipping away at adding books to the lounge's bookshelf as well, which is proving to be a more tedious task than I thought it would be. I'm going to try and include everyone's suggestions, but I'm going to have to populate the shelves with generic, unlabeled books just to fill in all the damn space...
Personally (working in a library), I wouldn't fill all the shelves to the brim with books, but leave some wiggle room here and there, and maybe even fill some excess space (or a few whole shelves) with decorative, evenly spaced tchotchke or bric-a-brac (classy stuff mind you... no green Orion dashboard-Hula dancers

). As much as librarians love their books, I know quite a few that like to show off wood grain shelves on the rare occasion they can. It's all about the "marketing." Oh, and you might even add some IKEA lighting to the Tchotchke shelves.
Heh, I also love
The Teachings of Surak right next to
Vulcan Love Slave. 
What is that like...
50 Shades of Grey (Green?) for the 23rd century? (I don't dare Google that at work)
Nice touch with
Falor's Journey too. I thought that sounded vaguely familiar.
For fun, you might even put up a book titled
Let Me Help authored by Patrick Koluuunahmeheheh Tajnaahme. If the Memory Alpha wiki is to be trusted, the final shooting script for
The City on the Edge of Forever listed that as the name of the author from Alnitak (Zeta Orionis) whom Kirk mentions to Edith Keeler with some high regard, for his use of the theme "Let me help." There's no apparent mention of the book's title however, but it's just for fun and would make a nice Easter Egg.
