I collect old cookbooks. I have tons, including ones from Fanny Farmer and from the Harvey House which served railroad stop meals. They were all published before cholesterol was discovered and are fun to read and try when I get ambitious and nostalgic. I also have recipes passed down through the generations of my and my husband’s families, including ones I had to force grandmothers to make in front of me while I jotted down the ingredients and estimated the amounts.
The Library of Congress has hundreds, if not thousands, of PDFs of old cookbooks. Tens of MBs a piece, with a number over 100MB.
