Under the initiative of Henry Osmaston, the International Association for Ladakh Studies (IALS) was formed At Herrnhut in 1987 with an international committee of distinguished scholars. Henry served first as Honorary Secretary and then – from 1997 until his death – as President of the Association. His life is commemorated online at henryosmaston.co.uk, the site contains tributes, obituaries and a set of pictures. These include two iconic photographs from his time in Ladakh and – even more revealingly – a picture of Henry in his study in the English lake district, surrounded by papers piled several feet deep. The website will be of interest to friends who knew Henry in the IALS, not least because of what it tells about his many other activities as a forester, farmer and university lecturer.

The functions of the International Association for Ladakh Studies are to provide contacts between all who are interested in the study of Ladakh, and to disseminate information about proposed and completed research and publications. To do this the IALS organises colloquia (usually every other year), arranges publication of the proceedings, and publishes a biannual newsletter, "Ladakh Studies". This includes information about conferences, planned and current studies, requests for specific information and help, short reports, publications and general information about Ladakh. The close integration of resources, culture and religion in Ladakh demands a holistic approach, and members of the IALS are concerned with a wide variety of topics. Membership is open to all who are interested in Ladakh; for further information apply to the Hon. Membership Sec.

In 2009 the
IALS Constitution was ratified at the Leh General Meeting.
