When you have entered, there is a tab called “select a Database”
On our last meeting, we looked at two of the databases: Web of Science and Journal Citation Reports.
In Journal Citation Reports you look at journals, their impact factor and other statistics about them. Human Rights, Humanitarian Law and International Law is all under “JCR Social Sciences Edition”. You can also search for a specific title, if you don’t know the exact titel, use * to truncate.

In “Web of Science” you search for Authors and Articles.
