Many libraries have massive free online book catalogs. LA is free if you live in CA, but you do have to visit a local branch. Philly is free in PA and $35 per year for out of state--a great resource, no gas costs, etc. I am avid reader and am happy to be rid of the cost (yes, even for .50 books add up when you go through one per day, and the cost of gas, as well as additional pain to drive, etc.).
