I was wondering if anybody knew some good level design books that will help me further my knowledge of level design

This website really helped me out finding my direction and whatever I need to learn. There are advance books of it as well, if you need them.

This is just me surfing through..I'll wait for someone to post a bit more legit link.

Search for a fella named Hourence, has a couple of great level design books I recommend. Also for architecture, check out Experiencing Architecture by Steen Eiler Rasmussen.

thank you guys so much...i just did a quick glance at http://www.worldofleveldesign.com/ before i leave at work and so far i love it..gives good insight on what i am doing wrong on becoming a level designer...
