I love Logos
- it is a fantastic digital library system that integrates so many great resources. I wanted to list one more reason why Logos Rocks...it will soon rock Charles Haddon Spurgeon. A massive collection of his works are on Prepub for just 250 bucks. The books would cost you about 1700...78 books at about three bucks a book. Not small dollars, but this is a crazy good deal for this amount of material.
