The second volume in Magnus Lindkvist's huge work on bidding deals with (1) Artificial Opening Bids on the One Level, and (2) One Notrump Opening Bids and Continuations.
The first part deals mostly with strong one club openings, but also covers other artificial one club openings and other artificial openings like the nebulous one diamond opening in Precision and one diamond forcing.
The section on one notrump opening bids and continuations is large, which shouldn't be surprising if you consider how many different notrump systems and treatments are used around the world.
