reading about W.H.F. Talbot - nice articles and book on Calotype?

I think salt printing (a.k.a. Calotype or Talbotype) is an interesting process with beautiful results.
I love printing with salt:


(BTW: I also like albumen printing - which is a similar process)

Mike Ware wrote a nice "summary" of W.H.F. Talbot's first endeavors on the interesting blog of Larry J. Schaaf, explaining the process and succes of W.H.F. Fox Talbot back in 1835:

A more extended article by Mike Ware can be found here:

Also an interesting read.

I'm thinking of getting his book: Mechanisms of image deterioration in early photographs - the sensitivity to light of W.H.F. Talbot's halide-fixed images 1834-1844.
Has anyone of you read this book?

I went to the exhibition in London:
(there was a url link here which no longer exists)
As mentioned in the articles by Mike Ware you quote, the tones obtained in the early prints I thought very pleasing, not matched by anything readily available today.
