There are an incredible number of really interesting white papers available free on the web that are great ediscovery and forensics resources.
Some of my favorite places to find them are:

I hate reading white papers on my computer, and I hate printing them. My solution - I load them onto my Sony Reader or Amazon Kindle.
The Sony Reader accepts the pdf documents in native format, but only the Kindle DX does. Sometimes though, the print is too small to read so I often prefer to convert the pdf to formats for the Kindle or Sony Reader. I rarely read books on my Kindle DX, but it has become a portable library of Forensics and Ediscovery papers.
