WEBSITE: Wikibooks Open-Source TextbooksSorry for the quiet this week. I'm back, I promise! My link for today is Wikibooks, a Wikipedia-based collection of nearly 25,000 open-source textbooks which can be both browsed and edited by visitors. You can search by category, Dewey decimal number, Library of Congress number or alphabetically. I browsed the cookbook section, and its small but growing collection of recipes of a variety of types was supplemented by links to Wikipedia entries on cooking techniques, nutrition topics and more.
