I just made this discovery, and it made me pretty happy-so I thought I would share!
I love Photoshop/Photography books but I hate the high prices, I found through my library that I have access to TONS of ebooks. The library site took me to http://proquest.safaribooksonline.com/home, I had to punch in my library barcode number to get access.
This is good because I can log in at home(or anywhere), look at just the chapters I am interested in, search by subject, and read at my leisure.
This is bad because reading books on line kind of sucks. I would rather have it in my hands, but until I can plunk down $40 on every book I want this will work.
Hope it works for some of you!
