Books

[JimDandy]

I recently bought a book note (Hammocks 5th rate), at the Admiralty store, clicked "use" and it disappeared.  I am hoping that this book will add Hammocks (extra crew), to the ships I craft in the future. Can anyone tell me if this is correct or if not, how do you use the Books function?

Thanks

It is added to the ship knowledge options.
