What do the Sumatran tiger, Philippine tarsier, and Galapagos land iguana have in common? They are all endangered or critically endangered species; they have all appeared on the covers of O’Reilly Media’s iconic software manuals; and they are all featured in the publisher’s new O’Reilly Animals campaign , which aims to mobilize the technology community to help save these species from extinction.

O’Reilly has been using old etchings of various animals as the covers for its programming books for decades and already includes some information on each species in the colophons of each book, but the new Animals campaign takes it further. The Web site presents detailed information on 10 of the animals (with more to come) as well as current technology projects that are aiding conservation efforts and a short list of opportunities where developers can volunteer their time and expertise.
