If you are not familiar with the Christian Research Journal it is published by Christian Research Institute (founded by the late Dr. Walter Martin). It has a variety of articles on its website, including some on Roman Catholicism.

Good evangelical books on Roman Catholicism can be identified (and purchased) at their store on-line: http://store.equip.org/cstore/parser.cgi?CTG=CTG-20&TMP=CRI+Category&SUB=ALL
