More than thirty years after the death of J.R.R. Tolkien there is still a steady supply of previously unpublished material becoming available.  In 1990 HarperCollins acquired Tolkien's publisher - Unwin Hyman (formerly George Allen & Unwin).  While much of the former A&U list was dropped or sold off to other publishers, HarperCollins focused their efforts on the Tolkien list and the approaching Centenary.  Many titles were re-issued in covers incorporating the JRRT monograph as a logo.  Christopher Tolkien continued to work on his father's manuscripts - publishing the remaining volumes of The History of Middle-earth series as well as piecing together The Children of Húrin from a series of unfinished drafts.

The Children of Húrin

Wayne Hammond and Christina Scull have become central to Tolkien publishing in recent years, writing or editing amongst others things J.R.R. Tolkien: Artist and Illustrator, Roverandom and the 50th Anniversary Edition of The Lord of the Rings.  The Peter Jackson-directed film adaption of The Lord of the Rings caused a renewal of interest in Middle-earth and prompted a flurry of Tolkien letters and inscribed books to be offered for sale by book dealers and auctioneers, with extracts being printed in their catalogues.  In addition, The Elvish Linguistic Fellowship is slowly but steadily editing Tolkien's linguistic writings for publication in Vinyar Tengwar and Parma Eldalamberon.
