Another thing is 'location'.If you are seeking a location for a shoot, a book cannot generally tell you where to find it. It is about scouting around, finding them for yourself. Yeah you can grab a landscape book of photos and wander off to the 'usual places', but if you want to get a unique landscape, you need to find the spots yourself.

Same can be said for outdoor portraiture. Wedding photographers will scout out locations before the big day, looking at light, shade, where the sun comes up, sets, etc.

Finding locations cannot really be learnt from a book. It can be copied, but to learn to find your own, and get a unique view/place, is something each of us has to do for ourselves. It comes with improving your photography, as you understand what compositions, light, etc make the best results, you can then start to find the best locations in your area.
