Hello,

I'm new on this forum, and just didn't manage to find my question by search term, even if I think that a shouldn't be the first one with that problem.

I decided to sort my library by date - not the date of the current edition, but of the content (first edition or creation). Like on my book shelves in the corridor. No big deal: Just created a user defined meta tag called "Original-Date" (well, indeed in German).

BUT: I can't enter values before the common era ("b.c.") How can I sort classical literature from Rome and Greece and other early cultures? There _is_ some media in the "free" world. I even can't set a date before Feb 0101!

Anyone an idea? Within or outside calibre?
