a consortium of natural history and botanical libraries that cooperate to digitize and make accessible the legacy literature of biodiversity held in their collections and to make that literature available for open access and responsible use as a part of a global “biodiversity commons.”
So much stuff here! Easier to navigate than Botanicus.org, too (and I think everything there is also part of the collection here). They have a Flickr photostream where they've already pulled thousands of images out of the texts for you, and you can download individual pictures instead of the whole book. I must warn you that you can easily spend hours on there. Proceed with caution! Did everyone already know about this and not tell me?
I might need these fish for Abe's nursery:
Or maybe this beaver for Milo and Gus' room:
Maybe you want some fox hunting illustrations? Yeah, I think you probably do, because these are awesome.
I could go on FOREVER! But you get the idea. I have big plans for a gallery wall in my dining room, and this sites figures very prominently in said plans.
