seaparate fiction, non fiction into 2 libraries

[cybmole]

as the thread title says - is there any simple way to reflag each book as either fiction or non-fiction., with a view to then splitting one large library into two. I do not currently have reliable tags & it would take far too long to do this by inspecting every book.

can I do this via a bulk metadata download operation, or my inspecting / manipulating ISBNs ?

ISBN would only work if the Publisher (or the parent co) Only published one or the other.

in addition, you would need a list of ISBN publisher number assignments as ISBN Publisher number is a variable length just to parse the ISBN

ISBN10: Language-Publisher Number-Book Number-Check digit (Mod10)
The total length is always 10 characters (dashes not included)

Without reliable Tags
