Meter Stamp Catalog?

Does anyone know of a meter stamp catalog?
I have a pretty good size collection that keeps getting pushed to the back. I would like to start learning about these stamps.

Thanks!

You should explore the webpage of the Meter Stamp Society:
https://www.meterstampsociety.com/

Thanks! That's a good start. Their site is very confusing but at least I now know the name of the catalog.
Just have to find one.

The online version --> https://en.wikibooks.org/wiki/Unite...tamp_Catalog

The online version is probably best.

When it came out the US catalog was $100.
There was a print update that was also digital, at some cost to new buyers but free to original buyers I just looked at it online.

The next update was also the move to google books, now entirely online and only updated online.

I tend to prefer an actual book, but having occasional updates is sometimes better. The only other US Meter catalog I'm familair with is from the late 1950's.
