A new microbiology textbook is available that I find interesting: Microbial Life, Second Edition, by James T. Staley, Robert P. Gunsalus, Stephen Lory and Jerome J. Perry. It is written for sophomore to senior undergraduates who have a general understanding of chemical concepts and biochemistry. Some free samples are available from the book, including two complete chapters in pdf format (Structure and Function of Bacteria and Archaea, and Taxonomy of Bacteria and Archaea), some figures and a powerpoint lecture. A companion website additionally provides interesting learning resources. After checking the free samples, it seems to me that the book has been edited with great care to content, illustrations and general aspect.
