What is currently the best book for the late dates? I noticed in the back of Penny-Wise an ad for a new set of books that cover 1816-1857 by Noyes. I already have the earlier Noyes book for 1816-1839, but I am still using Newcomb for the late dates. Is this new set a big improvement or should I keep using my older Noyes middle date book and perhaps buy Grellman's late date book for much less outlay?
What are you all using as a late date reference?
