I can explain why the Mark Bittman recipes are appearing - it's because we are proofreading some of his books. They were indexed in the very early days when quality control wasn't quite so stringent. Unlike a newly indexed book when the recipes all go live once the book is approved, as each recipe is saved it's appearing at the top of your list. I have Bittman books on my Bookshelf, but once I discounted these, all other recipes were coming up in the order they had been indexed. Try viewing your results with this search to see more clearly if they are still not in the right order.

Cheri - I think you'll find all those recipes from older indexed books are also Bittmans.
We are working with Mark Bittman to create a record of all his recipes and we agreed to include page numbers in his books - this isn't something we're planning on doing for all indexed books at this stage.
Deb - I can't reproduce your issue of a recipe appearing on your Bookshelf - if it happens again, let me know. You can delete it by clicking on the recipe name - if you hover over the 'Bookshelf' box under the title you'll see it changes to remove - click on it. You can only do this for individual recipes on your Bookshelf, not ones that are part of a book, magazine or blog you have added.
