To identify an unknown source, you must decipher the citation. Most citations will be familiar to you, such as cases or federal statutes. However, citations to secondary sources or more obscure primary law can be more difficult to understand. There are many resources you can use to help understand the abbreviations used in a citation.
Bluebook Tables
Bluebook Tables are helpful not just to create citations, but also to interpret citation abbreviations you don't know. Especially useful tables for identifying sources are:
Prince's Dictionary of Legal Abbreviations (2017)
