The aim of this paper is to show how books looked and explain how they were produced from the middle of the 15th century. By using new production techniques and changing the materials for book making, they take on a new form. The work is divided according to the periods in which there was a significant change in the appearance and production of the book. Book equipment are technical elements of a book such as shape and format, number and size of pages, covers, binding and other. Books used to be made by hand, including illustrations inside the book or on the cover. The techniques of book art advanced, but the importance of illustrations changed. In the earlier periods, great attention was paid to illustrations, but over time their significance decreased. It is important to point out who the books were intended for and in what language they were written and who the authors were. All this affected the quality of the material used and the decoration of the book. Books that were simple to make were accessible to a wider class of people due to their low price. The distribution of books, their content and accessibility speak volumes about literacy and the position of the common people in each of the periods. Over time, the book acquires new elements such as the title page and information about the printing and the publisher, thus taking on the appearance of today's book.
