Note: NSR keynumbers have the format YYYYAANN, where YYYY is the publication year, AA is usually (but not always) the first two letters of the first author's last name, and NN is a two-digit or two-letter code assigned to the reference. Since about 1973, digits have been used for primary references and letters for secondary references.
