Eight questions that I would like to know the answers to before I get a book related to my talent:
Is it simple?
Does it convey information quickly, without packing in too much useless stuff?
Is it accurate?
Does the author have experience?
What is the book about?
Does the author say why?
Does the author give simple yet effective examples?
Are the photographs, graphs, drawings etc. helpful, simple, and to the point?
