The usual textbook structure includes:

1. content
2. introduction
3. chapters
4. key words
5. bibliography

The key-word list informs the reader about the problem area covered in the book, and makes finding the topic the reader is interested in easier, while bibliography is a direction sign which enables the reader to supplement the described subject.

Each of the chapters is conceived in such a way that they cover a part of the subject matter, to contain the illustrative examples, as well as to end with questions and exercises through which students can

check whether they mastered the materials that were presented in the chapter.

- goals
- chapter abstract
- text
- examples used to illustrate the topic
- exercises for knowledge-check

A number of very good textbooks, especially the older ones, aren't structured in such a manner, because the illustrative examples, as well as exercises and problems for knowledge-check were printed separately, as mimeographed course materials.
