You would be surprised by how many folks do not even know what their local library offers.
I spend allot of time traveling and listen to books on tape/cd which I get from library. Should I buy em for upwards of $200+ for some series?
If I want to listen to them again I'll just check em out.
You can invest in your self and do so wisely.
Having said that I brought Savages book from MDRT site earlier today
