For some reasons, I need to keep 2 versions of a book into PDF: same book, different pdf files.

Calibre does not allow to keep more than one format of the same kind into the library, so I had thought I had found a workaround: zip the second pdf file and add to the record.

I did it with one book and everything went smooth: now the record shows 2 formats, PDF and ZIP. The zip is good for me for the first pdf is a matter of fact a copy without any changes, straight out from the scans, for backup purposes, a copy I get only if something goes wrong with the other one, to restore the file.

Well, after that book I tried to insert another one; I put first the pdf, and then the zip. This time, instead of adding the zip to the record as a new format of the same book, I just plain overwrite the other pdf with the one contained into the zip... Shit ;-) I guess Calibre recognizes the zip as a pdf for its content, unwrap it and accomodate into the record, deleting the old one. Correct, I guess, but not I would like it to do.

So I wonder how come in the first book it did not go that way and wether there is a way to reach what I want.

Thank you.
