Good books on investing?

[mattkime]

I'm considering opening an IRA so i can invest some untaxed money. However, I'm really not sure what I'm getting into. As a freelancer, I have to chose between putting money toward retirement and keeping it available to invest in my business. Currently, any money i have set aside for taxes is sitting in a savings account at 5% - which seems very good for a short term (and safe!) return.

Are there any good books out there on investing?
