Is it a book or not??

[Sylvia]

I own two books which accompagny a DVD series. The articles in the books give extra information and background on the cases handled on the DVDs.
My problem is that none of the books have no information about editor, no colophon at all. Only at the rear cover there's a number which doesn't look like an ISBN number.
Is it possible to add these books to GR?

Does the DVD series give more information about the companion books?

[Sylvia]

Not really. The series has been released by History Channel and was for sale at houseofknowledge.nl

The numbers on the books start with 8710114.... which is not a normal ISBN# I guess.

I though about putting them in GR with a library note, but as also author info is missing (required field) I first wanted to ask for help.
