A selection of some of the available research materials can be viewed here. This sheet can be accessed free of charge and, if you have a password, its contents linked to directly. It is well worth a look.
Year: Use this option for listing all articles published in that year.
Title: Search the title of articles in the database. If the full title does not produce a result, use a key word to search. For example, searching for The UN and Libya: Intervention or Interference by Qureshi QC will not produce a result. But searching for a keyword, such as Libya or Intervention would produce all articles including that word in their title.
Author: Try using the surname of the author rather than a full name. Some titles are listed with initials for the forenames.
Reference: If you want to search for a particular publication, then this option will list all items appearing in it within the database. Again, use a keyword.
