I suggest you don't use a Date column. Calibre doesn't seem to handle dates earlier that 1st Jan 101 properly, also you could get tangled up in timezones. Using a string representation will make it awkward to deal with authors like Homer, Herodotus etc etc

If you can select all books for an author, you can use bulk edit to change the born year in those books

Pity Authors can't have custom columns

Thanks

Ok I have create the column like your image, but now what I must enter in the virtual library?
