Adult book catalogues

Cataloguing means recording, describing and classing all kinds of cultural assets.
This is about finding and understanding such assets, appropriately documenting them, and filing any information about them according to accurate criteria.
The system used in our libraries is the Dewey Decimal Classification (DDC) System – invented by US librarian Melvil Dewey in 1873 and published for the first time in 1876. Currently, this system is the most widespread in the world, used in over 135 countries and has been translated into over 30 languages.
More generally, the DDC is divided into ten main classes, which cover all areas of knowledge. Such classes are divided into ten subdivisions, which in turn are composed of another ten specifications.
The more divided the class, the more specifically the subject is dealt with within the selected topic.
So the subject of a book is expressed by at least three digits, which are visibly posted on a label stuck to the spine of the book, which are GREEN if it is an adult book or YELLOW if it is a children’s book.
Such digits stand for the place allocated to the book, which is technically called Pressmark. In this way, all works dealing with the same subject are placed side by side on the same shelf. Every work, in addition to the index stating its subject or class, also bears the first three letters of the author’s surname or the title in the Pressmark.
