Directory for Smartdoll Heads?

Hey yall! I don't own a Smartdoll and only have a cursory knowledge of the different heads. I'm aware there's a handful of sculpts and multiple different screenings/faceups for those sculpts similar to a fashion doll brand. While I'd love if anyone has a list of the doll sculpts, what I'm actually looking for is a list of the different faces. The SmD site is kinda hard to browse through and constantly changing in terms of stock, and I kinda wanna make a list for myself of the heads I would most want and in what colors in a dream scenario. Does anyone know if there's like, a directory or guide out there for the releases?

Quite a while ago, we had a pretty comprehensive list here on the forum:

Unfortunately it's VERY out of date, but maybe it will provide a starting point for your research.

Literally an hour later and I find what I'm looking for! Here, for everyone else:

@PlasticJester  I can vouch for the accuracy and up-to-dateness of it. It's run by MyLadyDisdain and their people, so they're pretty good about maintaining it. It has been helpful to me in understanding the differences between some of the more similar sculpts, and keeping track of who is and isn't released in which colour.

I'm learning very quickly I'm incredibly picky on releases, and most of my favorite ones are either fantasy colored or candidates/prototypes lol
