References to legal journal articles are often abbreviated in the same way as cases, so if you don't know what an abbreviation means, you will need to look it up. The most useful index is probably the Index to Legal Abbreviations produced by the University of Cardiff at http://www.legalabbrevs.cardiff.ac.uk/
You might see a citation that looks something like this:
(2003) 62 CLJ 134
This is the 2003 volume of the Cambridge Law Journal. The volume number is 62, and the article you want starts on page 134. Normally, the author and article title would also be given, but this isn’t always the case.
