Canada FDC

Our Gallery has passed 10,000 images and it is time to talk about the next step - Catalogues.
I use the plural, because I don't believe a single catalogue that could satisfy everyone's desires could be made and would prove too unwieldy even if it could.
The greatest value in a Scott catalogue lies in it's identification of stamps and providing a number for each issue and variety. I don't believe we can achieve this with covers, there are just too many variations and unique instances. We might, however, be able to develop a standard way to describe a cover. 
Few would question the use of the Scott numbering to describe the stamps on a cover. There are catalogues of cancellations and slogans. There is a catalogue of Canada Post covers. I am not aware of any generally recognized numbering for cachets. I would like to see this site become the source of a standard numbering of cachets and for descriptions of covers.
To get there we will need to start mining the images provided in the Gallery and developing a series of catalogues. We have started with a couple of volunteers and a new section in the Gallery called FDC Cachet Catalogues. We will be starting with some recognized cachet makers. We have already started running into some interesting questions however.

• How do we number cachets?
• What information do we keep?
• What constitutes a variety?
• What do we do about generic covers?

I would like to hear from the people who expressed enough interest in FDC to join this site. What do you think?
