I hope people find these informative.
By the way - in the first Ilford link I posted about the basics of film development, there is a handy developer comparison chart on page 3. I don't recall seeing this chart in any of the more specific tech publications for the individual liquid and powder developers, so this is another one of those lesser known things which may prove useful in discussions about the relative working characteristics of Ilford's film developers. The table is sort of analogous to that Kodak developer comparison diagram with the diamond-shaped "sliders" roughly comparing sharpness, graininess, and speed.
I also highly recommend the the links above to Kodak's "Black-and-White Tips and Techniques for Darkroom Enthusiasts" (for negatives and printing) and this additional link I forgot to paste in:
Basic Sensitometry and Characteristics of Film
It is more basic than the "workbook" version and discusses film characteristics such as graininess and granularity, sharpness, resolving power and spectral sensitivity.
And of course the safelight tests from both Ilford and Kodak...
