The Larry Bartlett book is very enjoyable. The photographs are mostly in the classic reportage style. It clearly shows how L. Bartlett took the straight print to a finished print; many of which are quite stunning.
The Steve MacLeod book is also nice, but somehow left me a bit cold.
Eddie Ephraum's "Creative Elements" is full of impressive landscape pictures and loads of formulas (to make toners, developers etc from raw chemicals), but I can't help feeling that he overworks his prints with his endless bleaching and toning stuff; but the final prints are fantastic indeed.
But, Aristotelis, there are two books that I would definitely recommend: "Darkroom" and "Darkroom2" by Lustrum Press. They are rather difficult to find because they were pulished in 1977 and 78, respectively. Also, the print quality of the photographs is rather poor by todays standards. However, whereas most other books are monographic in that they show one persons methods, these darkroom books are a collection of the working practices of 23 photographers; and it's astonishing to find out how literally each of them does everything in their own unique way.
For example, Eikoh Hosoe says: "I prefer to use high contrast paper and a rather thin negative...", whereas Ralph Gibson says: "I overexpose, and overdevelop and, in the process, pick up grain and contrast. This yields a dense negative, but through the years I have found that I prefer them this way".
