What is a subject list?

A subject list is a list of networked electronic resources, which have been scientifically arranged by subject. A subject list assists users to find information quickly and easily.

For example of some subject areas (with direct link to the Searching by subject list)

Social science Technology Agriculture and forestry Medicine Natural science Informatics Economy

A subject list is arranged hierarchically. Each subject is directly connected to its matching databases. Several subject lists also function as a search engine.

Searching by subject list

Identify which subject the needed information belongs to, and then click the subject. For instance, to find resources about Local Area Network (LAN):

Choose subject: Informatics [] Computer network []LAN

Advantages of subject lists

Moreover, Subject list search narrows the results within the selected subject, which is more convenient for users than Google search that provides all results related to the selected keyword.
