Universidad de Extremadura Library Guide for International & Exchange Students: FINDING DOCUMENTS

What is a call number?

Every book in the library has a call number which associates it to a subject area. The call number is like a street address as it directs you to the location of the item on the shelf.
Make sure you write down the whole call number (e.g. 004.7HESana) so you can find the exact item you're looking for.
The following example explains the different elements of a call number:

• Author    Hesselbach Serra, Xavier
• Title  Análisis de redes y sistemas de comunicaciones / Xavier Hesselbach Serra, Jordi Altés Bosch
• LOCATION                          CALL NUMBER            T. LOAN
•  B.CENTRAL CÁCERES      S004.7HESana                  PR EXTERIOR
