"Restatements" are essentially model laws, designed to "clarify and synthesize" the common law in a particular field of law. Restatements are published by the American Law Institute (ALI). The ALI's Web site posts a checklist of all the current Restatement volumes and pocket parts. See the Publications Catalog to look up drafts.
Pocket parts to the volumes are mailed out annually. A list of the latest pocket parts for all volumes is included in the annual mailing, but it is not posted on the Web site. To get a copy of this list, or for other questions, call ALI at 800-253-6379.
Electronic Access: Current restatements are available on Lexis (2NDARY;RESTAT) and Westlaw (REST). The ALI posts a list of Lexis and Westlaw database names. Restatements are also available in PDF format in the "American Law Institute Library" on HeinOnline (subscription only).
Annotations: Each Restatement section is followed by extensive annotations. For even more, you can Shepardize Restatement sections on Lexis.
More information: See the Restatements page posted by the Loyola University Chicago School of Law Library.
