To me, hard copy books are passe. You can neither easily update them, nor download data from them. Even eBooks have this issue about downloading
You're going to be far better off getting familiar with the Wiki section at Scan Cape Cod, and the databases here. In addition, the Scan Cape Cod website has a forum devoted to programming files, and with a premium subscription and the right application, you can download data from the databases into your editor. There are folks on both sides doing updates, so generally speaking, if someone has submitted the data, it gets entered, somewhere.
