and Nevill Coghill. He published The Saga of King Heidrek the Wise: "Translated from the Icelandic with Introduction, Notes and Appendices by Christopher Tolkien" in 1960. Later, Tolkien followed in his father's footsteps, becoming a lecturer and tutor in English Language at New College, Oxford, from 1964 to 1975. In 2016, he was given the Bodley Medal, an award that recognises outstanding contributions to literature, culture, science, and communication. Editorial work His father wrote a great deal of material connected to the Middle-earth legendarium that was not published in his lifetime. J. R. R. Tolkien had originally intended to publish The Silmarillion along with The Lord of the Rings, and parts of it were in a finished state when he died in 1973, but the project was incomplete. Tolkien once referred to his son as his "chief critic and collaborator", and named him his literary executor in his will. The younger Tolkien organised the masses of his father's unpublished writings, some of them written on odd scraps of paper half a century earlier. Much of the material was handwritten; frequently a fair draft was written over a half-erased first draft, and names of characters routinely changed between the beginning and end of the same draft. In the years following, Tolkien worked on the manuscripts and was able to produce an edition of The Silmarillion for publication in 1977 (a very young Guy Gavriel Kay served as his assistant for part of this time). The Silmarillion was followed by Unfinished Tales in 1980, and The History of Middle-earth in 12 volumes between 1983 and 1996. Most of the original source-texts have been made public from which The Silmarillion was constructed. In April 2007, Tolkien published The Children of Húrin, whose story his father had brought to a relatively complete stage between 1951 and 1957 before abandoning it. This was one of his father's earliest stories, its first version dating back to 1918; several versions are published in The Silmarillion, Unfinished Tales, and The History of Middle-earth. The Children of Húrin is a synthesis of these and other sources. Beren and Lúthien is an editorial work and was published as a stand-alone book in 2017. The next year, The Fall of Gondolin was published, also as an editorial work. The Children of Húrin, Beren and Lúthien, and The Fall of Gondolin make up the three "Great Tales" of the Elder Days which
