Here are four books I recommend to introduce Reformed Theology. More books and materials can be provided. I hope to list free articles, audio, and video, and specific resources as well. While
http://www.monergism.com/ and such sites offer volumes of material, it is also buried among many other topics. I hope to make this site resolve primairly matters relating to the Doctrines of Grace and the Five Solas. Each of the books below are typically $13.00 or less. Invest $55 and 4 months (one book per month) on getting a good introduction to Reformed Theology, and in the meantime check in on the blog with questions for free resources too.
(I prefer the older white cover myself)
