How to cite a subsection of a book for IEEE
how should we cite a subsection of a book when a chapter is divided into multiple subsections, e.g. 2.1, 2.2, ... 


Rather than citing the entire book, e.g., [1], you can cite a particular subsection, e.g., [§2.1, 1], [§2.2, 1], ..., meaning section 2.1, 2.1, ... of [1]. With Latex, you can use \cite[\S2.1]{X}.
