This Resource Letter provides a guide to the literature on plasma waves and instabilities. Approximately 50% of the references are on linear waves, 25% on nonlinear waves, and 25% on applications. After each reference is a two‐letter code. The first letter indicates the level of the material. The letter E after an item indicates elementary level or material of general interest to persons becoming informed in the field; the letter I, for intermediate level, indicates material of a somewhat more specialized nature; and the letter A indicates rather specialized or advanced material. The second letter indicates the type of material, and is either T (tutorial), R (review), B (benchmark), or H (historical). An asterisk (*) in front of an item indicates those articles to be included in an accompanying reprint book. These are primarily benchmark papers. Material from in‐print books and review series, as well as most review articles, have been excluded because of page limitations.
