Hello,

I'm a new user of ebooks in general, of the Cybook Odyssey and Calibre in particular.

My question is about the date related tags.

I see in the metadata two tags : "Date" and "Published"

"Date" seems to refer to the Date when I have added the book to my library.
"Published" seems to refer to the date when the ebook was published.

Isn't there a tag for the fisrt date of publication, as a physical book ?
I like to know when a book has been published for the first time...

Thanks in advance.

Antonio
