In case this might be new to some members (it was to me), searching for a sanskrit phrase on-line I came across this on-line library of indian manuscript images of the Lalchand Research Library of the DAV college.

Some of them have transliterations and translations along with the manuscript photographs. I don't know how common this is in the collection. Looking at the Indology archives it looks like there was some mention of this project about 2000.

Thanks,
