He has written numerous articles on the linguistics of J. R. R. Tolkien's Middle-earth. He ran the scholarly mailing list Lambengolmor from 2002 to its closure in 2020. He is the editor of the Tolkien linguistics journals Vinyar Tengwar and Tengwestië. By arrangement with Christopher Tolkien, he edited and published a large volume of J. R. R. Tolkien's writings on his constructed languages in Vinyar Tengwar (in various issues between 1991 and 2007) and in Parma Eldalamberon issues 11 (1995) to 22 (2015). Reception John S. Ryan, reviewing the 2000 collection Tolkien's Legendarium: Essays on The History of Middle-earth (edited by Hostetter and Verlyn Flieger) for VII, called it a "luminous companion" to the 12 volumes of Christopher Tolkien's The History of Middle-earth, and "clearly indispensable". The book won the 2002 Mythopoeic Scholarship Award for Inklings Studies. The Tolkien scholar Douglas C. Kane, while welcoming the 2021 book The Nature of Middle-earth, writes that Hostetter "appears to overstep his role as editor" by presenting the materials according to his personal point of view. In particular, Kane states that Hostetter wrongly applies Tolkien's remark that The Lord of the Rings was fundamentally religious and Catholic to the whole of the legendarium. Kane calls this contrary to Christopher Tolkien's editorial practice, and "a blatant statement of intent". Kane quotes Verlyn Flieger's remark that Tolkien's work reflects the two sides of his nature; the work can be seen both "as Catholic [and] not Christian."
