What you've posted is a link to .pdf files that comprise "teasers" from the actual book. They are excerpts from the book with the intention of selling the full text.
Nice marketing technique, but these are not the entire book itself!
I recmmend Bruce Barnbaums "The Art of Photography"
I should clarify what I meant in my original post. By 'subject' I mean what sort of things will look best in colour and what sort of things will look best in black and white. Some things that look good in colour might not make a good black and white photograph and vice versa. These days I am shooting traditional Korean houses so I have a 'theme', as it were. Also, I am not a beginner and I already develop my own film and print at home (though I have just started printing so I am a beginner in that department). What I am looking for is a book that will be useful as a reference and to fill in the cracks of my knowledge of black and white photography. And, as I said in my original post, I want to learn more about filter use.
BWgirl, sorry for passing you over in my original reply. I checked the site you mentioned and it is not a free book, as someone else mentioned. And men definitely hear women; my wife never lets herself go unanswered. :)
Consider buying a 'PV' (Pan Vision) filter, typically dark olive-green, which reduces all colours to tones quite convincingly and mimics the sensitivity of panchromatic B+W film (hence the name). SRB makes one: www.srbfilm.co.uk. You can carry it in your pocket and just look at different subjects. There's a picture of one in the free module on B+W in the Photo School at www.rogerandfrances.com. Alternatively, any strong filter will do but it will distort tonal relationships more -- I've even used orange-coloured cellophane sweet wrappers.
As Geoffrey Crawley said recently, you can often make a picture in B+W where none exists in colour, so I know what you mean.
