If you wish to merge two books into one.
Select the book with the most complete or prettiest metadata. The record you want to keep.
Select the second book that you wish to merge into the first.
on a book go to edit metadata - Merge Books - Merge into first select book - delete others
(see attached) or
just press the shortcut key M
The second book will be merged in to the first book and the second will be deleted.
