Some of the papers require a background in linguistics or philology, or at least a deeper interest in language or Tolkien Studies. Arne Zetterson looks at recent work on one of Tolkien's special interests, the "AB Language" dialect of Middle English and its key text the Ancrene Riwle. T.A. Shippey explores the etymological background to some of Tolkien's words. Arden Smith writes about Tolkien's knowledge and use of Gothic. Carl Hostetter explains the failings of various neo-Elvish languages based on Tolkien's created languages, comparing them with a 19th century guide to English written by Portuguese who couldn't speak the language. And Michael Drout applies philological tools to the drafts of The Monsters and the Critics, tracing the rhetorical evolution of Tolkien's published lecture.
Charles Elston gives a brief biography of Blackwelder and Wayne Hammond surveys the role of special collections in Tolkien Studies.
I have read The Lord of the Rings many times and most of Tolkien's other works including much of the History of Middle-Earth, but nothing of broader Tolkien scholarship. So I found this volume a nice introduction to the variety of modern Tolkien Studies, as well as a source of insights into Tolkien and his work.
