This is got to be one of my favorite projects todate! And, it came to be because of the folk at "gracegems.org", who supplied the documents. There are a total of 31 resources. They were created using Logos 3.0a (the latest version). You will not be able to use these with only Logos 3.0 – let this be an encouragement to upgrade! Enjoy!
P.S. You can read a review of the book "The Precious Things of God", by Tony Reinke at Spurgeon.wordpress.
