I’ve been throwing together some new pages here with links to digital versions of useful books and papers, from some of the earliest lists of American birds to the once-standard, now shamefully ignored handbooks.
Eventually, given world enough and time, I suppose all of my e-bookmarks will show up on a page. Meanwhile, let me know if there is a corpus you’d like to see appear: if I have the links, I can post them.
Many, many thanks to the Biodiversity Heritage Library for making so much of our ornithological heritage available to us.
