It is not as big as some existing collections, however:
I have filled out a bunch of metadata for the keyboards, such as switch profile and spacing, number/types of encoders, and information about the common and less-common input devices
By limiting this to column-staggered and ortholinear keyboards only, it is possible to do a few more useful things, such as filtering based on column/row count (as if key count means much on smaller keyboards), key clusters, pinky stagger, or splay.
Apart of filtering, you can sort the keyboards, toggle visibility of columns (to only see what you care about), and generally sift through keyboards pretty quickly.
A few more pictures:

All in all, I hope that this will make it easier to answer "is there a keyboard that does X" type of questions
