I'm a fan of Ed Bain's work; I've used his trainer stats in the past, read his 4+30 book, and even read the book
Signers written by his wife.
After Googling him, I discovered that he still has an active presence on his website - you could get a Jockey Exacta report for the 6 September 2019 Belmont card, for example - and he's found time to write a new book,
Libraries, Yellow Cheese and 38,880 Running Lines. You can find more details here:
