Use the library catalogue
To find quality resources that you can trust start with the resources in the library.
Our library catalogue is the best way to find out what resources we have. There are dedicated PCs in the Learning Centre and you can also access our catalogue online using the link in the navigation bar above.
To help you to find a library resource on the shelves you will need to know its classmark (classification number). If you search for a book or publication using the library’s catalogue you will find the classmark below the title of the resource, in the list of results.
How does knowing the classmark help?
Non-Fiction Books & Publications
The non-fiction books and publications in the library each have a number and are arranged by subject, in number order.
The numbers allocated to resources are based on the Dewey Decimal Classification System. The numbers act almost like the address of the resource on the shelves, helping you to find it. Each number relates to a specific subject or subtopic of a subject.
The ten broad subject groups are:
000 – Computer Science, Information and General Works
100 – Philosophy and Psychology
200 – Religion
300 – Social Sciences
400 – Language
500 – Science
600 – Technology (Applied Sciences)
700 – Arts and Recreation
800 – Literature
900 – History and Geography
What do the numbers mean?
The numbers before the decimal point:
The first digit in the three digit number indicates the broad subject, e.g. 600 is Technology (Applied Sciences).
The second number indicates the division of the main subject, e.g. 610 is Medicine and Health.
The third number indicates the section within the subject division, e.g. 612 is Human Physiology.
The numbers after the decimal point indicate the specific topic covered by the resource in relation to the sub-topic. e.g.
612.1 is the Circulatory System
612.2 is the Respiratory System
Different books and publications about the same subject will have the same number, so at the end of the numbers you will also see three letters, which represent the author’s surname. For example, a book about the respiratory system written by Glen Bastian, will have the classification 612.2 BAS.
Resources that have the same number are organised on the shelves in alphabetical order by author’s surname.
Remember, you can also ask a member of the library services team for help.
