Parallel Tables

To help researchers navigate between the different Restatement series, ALI includes "parallel tables", found before the index of most Restatement subjects. These tables show corresponding section numbers between two series of Restatements. Some parallel tables may connect section numbers of the final Restatement with one or more earlier drafts. When using these parallel tables to find where an older series (or draft) section is located in a newer series, be sure to check all volumes of the current series - the parallel tables only point to the sections found in that particular volume.

The Parallel Tables found in the back of Restatement (Third) Unfair Competition show corresponding Restatement (Third) Unfair Competition and Restatement of Torts (1938) section numbers.
