The Elvish Linguistic Fellowship (E. L. F.) is a "Special Interest Group" of the Mythopoeic Society devoted to the study of the constructed languages of J. R. R. Tolkien, today headed by Carl F. Hostetter. It was founded by Jorge Quiñónez in 1988. The E. L. F. publishes two journals,Vinyar Tengwar, edited by Hostetter, and Parma Eldalamberon, edited by Christopher Gilson. There is also an online journal, Tengwestië, edited by Hostetter and Patrick H. Wynne; and it also sponsors the Lambengolmor mailing list.
In 1992, Christopher Tolkien appointed the editors of the E.L.F. to order, edit, and then publish his father's writings concerning his constructed languages. They have worked from photocopies of the materials sent to them and from notes taken by the group's members in the Bodleian and Marquette University Tolkien manuscript archives. It was agreed by all parties that the best way to do this was chronologically, as Tolkien's writings are often fully explicable only in light of his earlier writings, and often are dependent on those earlier writings for their context (both in internal and external terms). This main course of publication is being carried out in the journal Parma Eldalamberon. There are, however, some writings that are largely independent, and/or whose context has been sufficiently established by Christopher Tolkien's own chronological publication efforts in The History of Middle-earth, and so do not have to be presented in the normal chronological flow of the larger project. Such materials are being published in the journal Vinyar Tengwar. Members include: Christopher Gilson, Carl F. Hostetter, Arden R. Smith, Bill Welden, and Patrick H. Wynne.
Parma Eldalamberon (broken Quenya for 'The Book of Elven-tongues') was founded in 1971 as a fanzine devoted to a variety of invented literary languages, published under the auspices of the Mythopoeic Society. Today it is an irregular publication dedicated to the editing of Tolkien's manuscripts describing his Elvish Languages. It is edited by Christopher Gilson. It has no ISSN or ISBN number. Parma Eldalamberon is sold on a per-issue basis only, it is not found in bookstores.
