Dear Colleagues,
I was recently in Chennai and it appears that it is easier to have access to the MSS of the GOML than to obtain a book published by OUP!
At the GOML, I was able to get 5 MSS within 15 minutes and to photograph them.
As for OUP, on Anna Salai, this is now a show-room only. You can see the books. You can touch them. You can smell them. But ... you cannot buy them! A new regulation has been in force for the last 8 months preventing OUP to directly sell its books. You now have to go to a bookshop or a distributor. If the book is not there, they might be able to order it for you to OUP.
Good to know also, the TNSDA (Tamil Nadu State Department of Archaeology) has started to upload pdfs of its own publications and pictures/scans of paper and palm-leaf MSS on a dedicated website:
