Researching Secondary Sources in Law

This guide is designed as an introduction to researching secondary legal sources. Secondary sources are about the law rather than the law itself. They are great research tools that can save you time and money.

Overview

A legal treatise is a book or set of books on a legal topic that are written by experts. Sometimes students get confused between "treatise" and "treaty."   A treatise is a scholarly book or set of books about a legal topic. It is a secondary source. A treaty is a primary source legal agreement between countries. A good treatise is thorough, explaining and even critiquing, the law. A treatise can be an extremely useful secondary source for research because it gathers such detailed information on a particular legal topic or issue into one publication. 

If you practice in a certain area of law, you will become familiar with the well-known and highly respected treatises in that area. If you are unfamiliar with an area of law, consult a research guide on that area of law written by a law librarian.

Updating

Many treatises are updated by pocket parts or supplements.  Some treatises, known as "loose-leafs" are updated by new pages being inserted into a binder.

Search the UC Library Catalog

Always check UCLID first to see if a book is available in our library or another UC library. Note that even if checking out a book for a UC journal, YOU and not the journal are responsible for that book.  Be sure and renew and return your books as needed.

When you find a title through UCLID, the online catalog, that is owned by another library:

  • Click on the Request button. 
  • Enter your username and password
  • Select Law Library as your pick-up library
  • Click on the Submit button.

The book will be delivered to the Law Library and you will receive an email in your UC email account when it comes. Be aware that it may take 3 or more days to arrive. Note that if your pick-up location and request location are the same, the request is not processed. In other words, if a book is available in the law library, do not request it. Instead retrieve the book yourself and check it out.

OhioLINK Catalog Search

 If a book you want is not available at UC, you may be able to find and borrow it through the OhioLINK.  Be sure and check UCLID first.  OhioLINK is also accessible through UCLID (click the search OhioLINK button)
