My book tells me what the card is but not the number and diamonds part.
If you're talking about what usually appears as small playing-card inserts (or insets) with a suit symbol and a number or image of royalty, you could do worse than get Caitlin Matthews' book, The Complete Lenormand Oracle Handbook. She covers it all in admirable detail. Some decks just include a number or letter and a suit symbol in the corners without showing the actual playing card.
There is also good info on this in Andy Boroveshengra's book, Thirty-Six Cards, which I heartily endorse and recommend.
You can't go wrong with Andy's book as well. He used to post here as andybc but I don't know if those posts are still available. We used to have some great discussions.
you can read all about that in my free pdf book http://fav.me/d9sqzk0
