DHL is using several classification schemes for cataloguing of external materials.

UDC (Universal Decimal Classification)

UDC (Universal Decimal Classification)
Back to the top

Universal Decimal Classification was originally derived from Dewey Decimal Classification (DDC), and managed by the organization now known as the International Federation of Information and Documentation (FID). It was first published in French, from 1904 to 1907. UDC is an indexing and retrieval language for classifying information on all subjects and in all forms.

The following classification schemes have been designed in DHL to serve better management of the DHL collections.


UNX. Classification

UNX. Classification used for cataloguing materials about the UN. Each UN body has designed number.

Examples:

UNX.1

- UN in general
UNX.12 - UN Charter, text
UNX.15 - UN Security Council
UNX.21 - International Court of Justice (ICJ), etc.


Country Classification
Back to the top

Country Classification is the special classification scheme for government and international organizations publications located in the ESA Collection and Main Country Collection.

The Call number consists of the collection symbol (Main), the international organization symbol, or the country symbol, the category symbol and two or more digits providing specific identification for the publication by placing it in alphabetical order according to a «Short Cutter». The following «Short Cutter» is currently in use:

A E IL O R UY

The «Short Cutter» is derived from the first digit of the title for official publications and the first digit of the main entry of non-official publication.

Examples:

Jam     Jamaica. Department of Statistics
P26      Building statistics of Jamaica
[for ESA Collection]
