Thank you to everyone who responded and provided me (and some participants) with valuable information.
I felt that one question was not clearly answered until the final response from BetterRed.

in 1. I wanted to know whether the book was updated only in the dispatched book, or the original as well.
BetterRed's answer seems to be indicated by the fact that books would need to be imported back to get the changes registered.

In 4, as a result of that conclusion, I wanted to know why the change is made in the copy departing and leaves the original. Why not change the original and then dispatch a copy.

I understand the 'hands off' aspect of the library, but with photography the same type of library can be used but the metadata (keywords or categories) are usually saved direct to the photographs as well as the database. In that way it is always safe to assume that 'any' database could be constructed from the metadata contained in the images and a specific database is not required. At the instant the keywords are added to the database, they are written to the image and it takes a fraction of a second.
If a 'session' of key-wording takes place then the user equally suffers the same time penalty mentioned in the first reply.
I note that if an author is changed the (sometimes very large) books are moved, which is no less time consuming and makes the folders inviolable. Why is that not considered equally bad to updating metadata? In fact a faster operation in itself.

This is not criticism but a genuine attempt at fully understanding.

I wonder how many cries for help there have been in this forum because somebody 'made a mistake' or lost their 'presence of mind' or moved several books because they were doing some disk tidying etc. etc. and did not remember/realise that it would screw their Calibre, simply because that was farthest from their mind.

Question 5.
When the library is moved, by invoking the wizard, does the new library have the metadata written to books?
I am unable to tell, through lack of knowledge of book metadata. I did this and noted that opf files were left in the old library, along with any non essential files.
