Brandon Adams has created an excellent site designed to explore the specific contours of Reformed Baptist covenant theology as summarized in the 1689 London Baptist Confession of Faith. There are several interviews with Dr. Jim Renihan, Dr. Richard Barcellos, and Pastor Sam Renihan which contrast the 1689 Confession of Faith with the Westminster Confession of Faith, dispensational theology, New Covenant theology, and 20th century Reformed Baptist covenant theology. There are also some helpful charts and a section of recommended books. There is good stuff here — http://www.1689federalism.com/
Also, three “ordinary fellas” have put together a website called The Confessing Baptist (http://confessingbaptist.com/) which is designed to be “your one-stop shop for all things Reformed Baptist” (from the “About” section at the site).
