I am writing an introductory-level book about civil engineering and construction. I list the references at the very back. I show the title and name of the author at a minimum. Do I need something else? Is it obligatory to use a special format?
And no, I am not going to list specific page numbers from each, because from them I use information from many places and I lost track of what pages I looked at anyway.
Actually, the information I use is general and widely established engineering and construction information, which would be available in many other sources too, and whenever I use something specific I say it within the text anyway (i.e. per xxxxxx) so may be I do not even need to list references? I am an engineer myself so most of these things I already knew.
