A few bits of information I've come across that might be useful along with a few things I've written:

• Some manuals for old cameras
• The supporting material for an introductory course in medical statistics I used to teach to dental students
• The lead section has a paper giving the lead isotope data for some samples of galena from the Northern Pennines, England and a database of lead isotope analyses of Mediterranean ores
• A bit of software: some simple shell and perl scripts to make some command-line tools easier for me to use.
