Just found this new blog post by Sean Costello (ValhallaDSP) with a list of resources on artificial reverberation:

Super grateful that he is so generous with his knowledge. He probably knows more about reverb design than any other person on the planet.
@paul yes, many digital reverb i saw in the will pirkle book have precise delay lines sample counts for a very precise sample rate ( usually lower than 44.1khz )
@nonmateria plateau yes, haven't studied erbeverb. Clouds reverb and mverb are other implementations I know of based on dattorro.
Variable sampling rates can be tricky with reverbs!
