[MinervaCats] publication date issue

[hollywil@pittsfield.lib.me.us]

Hello my fellow catalogers.

Since Bonnie is on vacation this week, I'm hoping some of you folks could help me.  I have a 
book issued 2006 and 1997.  It is an updated edition (says so on the cover) BUT it has the 
same ISBN as the original 1997 edition.  Can I add my book to the 1997 edition and add the 
new date or will there be two different bib records with the same ISBN?

TIA,
