Few people open up the code and start reading it from start to finish.   Instead, a researcher will either open up the code to a specific section or will use an index to find the section for which he or she is looking.   Each of the three versions of the code has an index that appears after the last regular volume.  Pictured above is the 2001 index for the U.S.C.A.  (Each year a new edition of the index is published).   All of the indexes for each version of the code attempt to accommodate the transition from lay terminology to the language used by lawyers and legislators.  While you are getting familiar with a new topic, it will take you many attempts at looking up words in the index before you find the right words.  Often you will look up one term and be referred to another. (This is known as a 'see reference.')
