Building a Resource Library

What are some of your top resources for studying besides the "Halley's Bible Handbook" and "What the Bible Is All About Bible Handbook"?

Keep a database of messages and notes from yourself, close pastors, and other pastors. Listen to several sermons a week from different pastors to get ideas from and see different communication styles. 

Go to God’s word, go to the original language. See if anyone else has made messages on this and listen to them. Educate yourself and let your studying be organic. PC only reads commentaries if he’s completely confused.
