The American Bar Association has published a number of books on model jury instructions by topical practice area, as shown below.
To find other books on jury instructions, search in the Library's catalog, for subjects: "Instructions to Juries (State)" or Instructions to Juries United States" for federal publications.
Both Lexis and Westlaw have a folder of databases on jury instructions. There is a lot of overlap, but check each service to see what's covered.
