Greffy
A genealogy reference finder for the books already on your shelf.
Search for a topic and find where it is discussed in industry guides. Results give the book, the entry, and the page or paragraph, so you can turn to the source yourself.

Greffy is built from the printed indexes of seven works. If you notice something wrong or missing, please tell me. Suggestions fall into three kinds.
An entry missing from one of the seven. A heading you can see in the printed index that Greffy does not return.
An error in something Greffy returned. A page number that sends you to the wrong place, an entry worded differently from the printed index, or a result that does not belong under the term you searched.
A reference guide Greffy should add. A work you reach for often enough that its index belongs alongside the seven already here.
