Together with a group of friends I share a Dropbox-folder.
We all have separate catalogues, all with free ebooks, in total over 5000 of them.
Of course the catalogues have "doubles".

Is there a way to produce a "total" catalogue or an overview of all these books, without all the double entries, which are sometimes written in a slightly different way?

I was thinking of OpenOffice Calc but maybe there is a much simpler solution?

Many thanks in advance for your time.
Len.
