were the only unified collection of Tangut Buddhist texts in the world. With the support of the Scandinavian Institute of Asian Studies (where Grinstead was now working) and with funding from the Tuborg Foundation, a plan was put into place to preserve and publish this collection of Tangut texts. Grinstead was editor of the facsimile edition (comprising 2,249 pages, with six or eight Tangut sheets per page) that was printed in 1971 in New Delhi under the title The Tangut Tripitaka. Grinstead's major publication was his Analysis of the Tangut script (1972) in which he analysed the structure of the Tangut script, and assigned a four-digit 'Telecode' number to each Tangut character in an early attempt to assign standard codes to characters for use in computer processing of Tangut text. The book also includes an English–Tangut vocabulary list, and a study of the Tangut translation of the Classic of Filial Piety (Xiao Jing) in which Grinstead transcribed the very hard to read cursive Tangut characters of the text into their standard forms, which was considered an important achievement by other Tangut scholars. However, the book has been criticized as being difficult to read, having a 'haphazard' structure and an 'allusive' written style. Analysis of the Tangut script is a version of a PhD dissertation that Grinstead submitted to the Faculty of Philosophy at the University of Copenhagen on 29 November 1971, and which he defended on 30 January 1973.
