This site is slightly bare at the moment, however, I've been posting a fair bit lately to my blog.
For the moment, though, you might want to check out the US Navy Electronic Warfare Manual I collected (and put back up on the web to keep it from being made unavailable) as well as the entire NEETS (Naval Electrical and Electronic Training Series) set of electrical and electronic technician training manuals. I also have up a small collection of miscellaneous rescued documents.
For the more philosophically minded, I also have my collection of occult documents up. While I haven't finished doing all the PDF conversions I intend to do, there are still a few interesting things up here.Many of my documents are in PDF format, so you'll need either Adobe Acrobat Reader or Sumatra PDF to read/use them. Note: if you are using an older computer to access these e-books, I recommend using Sumatra rather than Adobe's reader, as it is considerably faster on older hardware.
