For the description below, develop an E-R diagram:

A book is identified by its ISBN number, and it has a title, a price, and a date of publication. It is published by a publisher, each of which has its own ID number and a name. Each book has exactly one publisher, but one publisher typically publishes multiple books over time. A book is written by one or multiple authors. Each author is identified by an author number and has a name and date of birth. Each author has either one or multiple books; in addition, occasionally data are needed also regarding prospective authors who have not yet published any books. A book can be part of a series, which is also identified as a book and has its own 2 ISBN number. One book can belong to several sets and a set consists of at least one but potentially many books.
