I highly recommend "Silver Spoon". Published in 1950s - about 2000 recipes - Indexed thoroughly - I use it both for its recipes and also for its heft as a doorstop.
Oh, I got the German version from my sister for Christmas once. I should really try to make some recipes from it, but it’s so much more work to look them up offline ;)
