Each year for Darwin's Birthday party, TPP puts out his Darwin library for students to peruse, and Alfred Russel Wallace's Malay Archipelago is put out too. The Malay Archipelago is Wallace's "Origin" and it is a worthwhile read. Wallace is a curiosity to my students, and most of them have never heard of Wallace showing just how badly the historical aspects of science are being neglected these days. Well, good news, everyone! All of Wallace's publications are now online and available for free. Such a deal!
