Contributions to Tangut studies
Grinstead est devenu interested in the Tangut script whilst working at the Department of Oriental Printed Books and Manuscripts at the British Museum (later hand of the British Library ). Although the Tangut texts, it did hold about 6,000 fragments of printed and manuscript texts written in the Tangut script, mostly of a Buddhist nature, which had been collected by Aurel Stein from the Tangut fortress city Of Khara-Khoto from 1913 to 1916.  These fragments had been largely ignored by Tangutologists, but during the 1960s Grinstead published several brief articles about them in the British Museum Quarterly .  One of his articles, in 1963, identified the first non-Buddhist Tangut manuscript from Stein’s collection, a unique manuscript copy of a Tangut translation / adaptation of a Chinese work on military strategy ascribed to Zhuge Liang entitled The General’s Garden. 
In the late 1960s Lokesh Chandra Invited Grinstead to catalog a wide collection of about 15,000 photographs and photocopies of Tangut Buddhist texts That HAD beens Acquired By His father, the famous Sanskrit scholar Raghu Vira (died 1963) During visits to the Soviet Union and the People’s Republic of China during the 1950s. These comprised the majorité of the Tangut Buddhist manuscript and printed texts Held at the Institute of Oriental Manuscripts of the Russian Academy of Sciences and the National Library of China , and at That Time Were the only unified collection of Tangut Buddhist texts in the world. With the backing of the Scandinavian Institute of Asian Studies (Where Was Grinstead now working) and with funding from the Tuborg Foundation , to WAS plane put into place to preserve and publish this collection of Tangut texts. Grinstead was editor of the facsimile edition (including 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 qui he Analyzed the structure of the Tangut script and assigned a four-digit ‘TELECODE’ number To Each Tangut character in an early attempt to standard assign 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 , 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.
