The Dewey Decimal Classification is a versatile system that adapts to the needs of different types of libraries and allows users to autonomously find their way around the shelves.(Find out more about Dewey Decimal Classification).
The collocation of a book consists of two parts:
- a numeric part which is the Dewey Decimal Class notation;
- an alphabetic part consisting of the first 3 letters of the author's last name or, in the presence of the editors, the first 3 letters of the title.
Dewey class notation numbers are not read as whole numbers but as decimals, that is, digit by digit so that for example 346.45066 will precede 346.4507.
To find the book on the shelf:
1. Search the title you need through the Luiss Library Discovery
2. Check the availability, the location, and the shelf list of the book
3. Click on the map it button to display the position of the book on the shelf
