Wexlers's site is always a good one also, but not of his dies are listed on his site yet. IE: when he came out with his publication of 1959-D WRPMs, they go up to 111 dies for this year. His 1960-D WRPMs would be two or three volumes like this 1959 book. While I'm interested in see this publication come out, it would be nicer to have it online with all dies present. That way when new dies are discovered, they can be added. (can't do this with a book) But would probably buy the 1960 and 1961 books when they come available.
