Thanks to everyone who wrote to tell us about their favorite cookbooks. The submissions ranged from the venerable "Fanny Farmer Cookbook," to obscure titles such as those compiled by local cooks as fundraisers for clubs and schools. In the hands of the right cook, any cookbook will work, especially the well-loved ones with stains and tears and notes scribbled in the margin.
Multiple submissions came for some books, such as "The Joy of Cooking," a staple of kitchens everywhere. Some of the titles are available in more recent editions at Amazon. For people searching for out-of-print books, those published only locally, or anyone seeking to replace an old friend that has gone lost, I suggest checking eBay, where nothing is lost forever.
The following are those we have compiled so far:

Favorite cookbooks
Marjorie (Young) Zwicker,
Bridgewater, N.S.

"My very favorite cookbook is 'The All New Fannie Farmer (Boston Cooking School) Cookbook (Tenth edition) which I received as a bridal shower gift in August, 1968. Over the past 38 years I have purchased (or received as gifts) numerous other cookbooks, but none can compare to my 'Fannie Farmer.'
"Although the cover has become separated from it, and most of the pages are dog-eared and wrinkled from use, it has the best presentation in plain, everyday language for absolutely everything and anything one would want to prepare in the kitchen. Just couldn't do without my 'Fannie Farmer."
