This could be one of the most interesting reads you might do on a long airplane flight... The following link is to a download of the 813 page .pdf file of
The Household Cyclopedia, which is a book of general knowledge published in 1881. I'm not suggesting that you download the entire book, but that you take a look at the Index pages from page 9 through 13 to see a subject that might interest you. The Cookery sections are fascinating! Click on the page that the link directs you to for your choice of what type of file you wish to download...
