Well, you know that The Complete Work of Charles Darwin Online is now live, right? But remember to give some love to the R.A. Fisher Digital Archive, where you can read his genetical and non-genetical papers. Also, keep an eye over at Abebooks for cheap copies of The Genetical Theory of Natural Selection. They're all north of $65 US dollars right now (that's like $2,000 Canadian right?), but I got my copy for $33, so just keep checking.
