Gary,
I have a Volume J (latitudes 40º-44º) of HO 218, but I have never played with it. I didn't acquire the book (at a used book store) until well after we discussed 218 here back in 2011. Was 218 ever popular for marine navigation?

And don't forget HO 218 which was widely used in WW2 flight navigation. It was the precurser to HO 249 with separate tables for stars and solar system objects, was published in multiple volumes each covering five degrees of latitude.

Dale,
There are dozens - just check out an old Bowditch. However, not all are considered "mainstream". In addition to the ones you listed, some other popular ones are (or were) HO208, HO214, Weems Line of Position Book, and, maybe, the S-Table (which was published in the Nautical Almanac for a few years in the '90s).
