In my University there is a specific in Harvard referencing, please find attached the document with the style of referencing.
Also it must be not only textbooks, it must be academic journals.
Also the references in the text must be not only in brackets, but also it is important to use such words as according to, introduce,confirm, propose, state, explain etci??.
