Contacting Dave

To avoid Dave's e-mail address being harvested by Spam engines, it does not appear anywhere explicitly on this web site. Instead this site uses a unique tool called a CAPTCHA to reveal the e-mail address ONLY when a human being has correctly interpreted some printed text. What is unique about this particular application of the CAPTCHA process is that while protecting the e-mail address from being harvested automatically by spammers YOU will be helping to digitize books! About 60 million CAPTCHAs are solved by humans around the world every day. In each case, roughly ten seconds of human time are being spent. Individually, that's not a lot of time, but in aggregate these little puzzles consume more than 150,000 hours of work each day. reCAPTCHA make positive use of this human effort by channeling the effort spent solving CAPTCHAs online into "reading" books. Currently, you will be helping to digitize books from the Internet Archive and old editions of the New York Times.
