Michigan State University has a collection of digitized historical cookbooks! Lafcadio Hearn's La Cuisine Creole (yes, that Lafcadio Hearn) and Frank Hamilton Cushing's Zuni Breadstuff immediately caught my eye, but the real find for this blog is Ardashes Hagop Keoleian's The Oriental Cook Book, New York, Sully & Kleinteich, 1913. 'Oriental' here means Middle Eastern, and really, Armenian. (A lot of fish dishes, which I'd guess aren't often made any more.) You can download the scanned texts in PDF, or read transcriptions on the site.
As long as you're downloading massive PDFs, you might as well get some music as well! The Rub has an ongoing history of hip-hop in mp3 form. They're up to Volume 21: 1999. "No Rubber, No Backstage Pass" with Biz Markie? I thought I imagined that.
