What are good photography books for enthusiasts?

Preferably books about still life, black and white, portraits and people. I really like still life and B&W shoots but I really need to up my game on portraits and people since I also photograph family during occasions. Oh and if they can be downloaded from the internet as well. Author and books title and content would be very helpful. I'm not studying photography but I really love to shoot. I have a Nikon D3000 for now and a 35mm lens and external flash.

There are lots of books on portraiture. Bill Hurter, Jeff Smith, Bryan Peterson, any of the big time wedding photographers are all places to look. For old school, Monte Zucker. I'm not sure who has on-line books. For portraits you will need a longer lens than 35mm. The 50mm f/1.8 makes a great budget portrait lens on a crop frame sensor.

A longer lens would be better for portrait photography - 50mm f1.8 or the 85mm f1.8.

This may be slightly off topic, but this series of 3 titles are downloadable (free) ebooks about candid street photography in B&W;
