Hmmmm.....Loved reading all the replies. Having once worked in a bookstore, I tend to use the system that was used there.
I have a large library upstairs and it is still overflowing. Stacks of books coming in , or stacks of books for a specific project.
I have a small bookcase in the kitchen of books I comonly use.
Books on the coffee table, books and magazines in the office. Let us not forget the bedroom.
But when I do sort them and get them all pretty. It is like this:
Location Regional. I am here in Texas. (Womans clubs, church and organiztions are kept sepearate)
By Author
Healthy (vegan, vegetarian, low-fat, WW, and so on)
Appliance (bread machine, pressure cooking, blender, etc.)
Grilling and BBQ
Ethinic (Italian, Chinese, Vietnamese, Thai, French, etc.)
Wine and drink with Entertaining at the end.
Putting away food.
Best of books. (like Food and Wine, Bon apetite', Gourmet, Cook's)
Desserts/Baking
Food Writing (They have great stories and recipes)
Historical Cooking (Old Virginia, chuckwagon, Presidents, etc) books published before 1900
I hope nothing was left out. I think you get the big picture though.
P.S. Thanks for asking.
