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.
In 1995, with the support of Christopher Tolkien and permission of the Tolkien Estate, Parma was reinvented as a series of standalone volumes publishing in full material from Tolkien's manuscripts relating to languages and scripts. Much of this material was previously unpublished or published only in heavily edited form (for example, selections from the "Gnomish Lexicon" published in full in Parma Eldalamberon #11 were published in the Appendices to The Book of Lost Tales.).
For a list of material by Tolkien published in Parma Eldalamberon 1995 to date, see Tolkien research.
The latest issue of the journal is number 20, published in August 2012.
