Since most of my expensive undergraduate engineering and science textbooks, which were valuable reference materials, were destroyed when Hurricane Katrina flooded my apartment, I'm looking for replacements. Specifically, I'm looking for freely available replacements on the Internet(s). Having found a free Linear Algebra book previously, I surmised that more must be available. I was correct. Here is what I've found so far:

• Physics: Motion Mountain
• Physics: Newtonian Physics
• Heat Transfer: A Heat Transfer Textbook
• Chemistry: The Chemistry Virtual Textbook
• Calculus: Elementary Calculus using infinitesimals -- I had this one already, actually
• Other Maths: There are a TON here
• Multivariable Calculus: here
• Electric Circuits: Lessons in Electric Circuits
• There is a ton of stuff at WikiBooks

Time for a coffee break. Apparently 7 hours and 50 minutes was not enough sleep.
