I think this bears emphasis. Many of us are asked to revamp listings in price guides. If a collector takes on the task of revising a guide listing, I think it is reprehensible to omit information on what cards are scarce. Give it all to the editor and let the editor decide, or don't participate at all, but don't agree to provide expertise and leave a misimpression with people counting on your volunteered expertise.
