MarciK - you list the books you own that you are surprised are not yet indexed. I can guarantee you that if every other member listed their books that they would like to see indexed, each list would be different. We do understand that all members would like all their books to be indexed but you all own different books. It costs us on average 5 years of a member's fees to index each book so it is never going to be possible to index every new book published. I can give you specific answers for the books you listed:
Delish: Insane Sweets - none of the Delish books have been very popular with members, with the exception of Delish: Eat Like Every Day's the Weekend which should be indexed soon.
The Bacon Bible - only 18 members have bought this book since it was published in April.
Christmas: Feasts and Treats (Donna Hay) - we do index most of Donna Hay's cookbooks. This one hasn't proved as popular as her other Christmas book but it is likely we will index this one at some point.
From Crook to Cook - this book was published more than a year ago but is on only 36 Bookshelves.
The Family Table: Recipes and Moments from a Nomadic Life - this book was published more than 18 months ago but is only 18 Bookshelves.
Don't forget that member indexing is available for any of these books you are very keen to get into your recipe searches!
