Annotations of cases citing a Restatement section can be found in the Appendix volumes the Restatements in print. There may be one or many Appendix volumes. They are organized by Restatement series, (i.e. citations to the first Restatement, then second, etc.), then by section number. Appendices are not cumulative. The spines indicate sections and years covered.
You can Shepardize a Restatement section on LexisNexis using the following formats. Note that Bluebook citation format for Restatements, or permutations thereof, will not work.
You can also KeyCite a Restatement section on Westlaw using the following formats. Note that KeyCite finds significantly more citing material than Shepard's for Restatements. (See the KeyCite Publications List for additional help with citation format.)

The Restatements are updated with pocket parts, cumulative annual supplements, and semiannual pamphlets called Interim Case Citations.
