LibraryThing Book Cataloguing Service
Wow, did I stumble into an incredible library cataloguing service. It's called LibraryThing - have a look at my Masonic and related library.
I've added a sidebar to the FMFD website , mostly because the nice Dummies folks wouldn't allow me to add footnotes or a bibliography to the book, nor would they let me publish a list of recommended books for further study. Fair enough, they are not in the business of selling other people's books.
So, if you want to know where I got my research from, have a look at my library list.
