Query: A life raft in a sea of confusion!

This book got me through Microbiology lab--easy to understand, and thorough. Everything you could want to know about a bacterium or a species is detailed here for you! I'm not selling this one back! Get this if you don't want to be writing reports in the middle of the night, going "oh, shoot, I didn't look up this or that bit of information in my professor's copy!"worth it's weight in gold!
