I own a Va Jr League Cbook which I treasure.
But I actually found a bookstore in a Georgetown, DC mall which carried every single Jr League Cookbook ever published.
food. com web site also has several Jr League recipes.
B&N once carried an encyclopedic Jr league Favorites Cookbook.
Checkout alibris.com----has OOP books from all over.
Make sure to check out the no-bake "Rum Balls" under Desserts..I've made 'em..yum...and one time when I was out of rum, I used bourbon...
