Mathias Metzger has made available a nice resource for scholars in Rajasthani studies. I stumbled across it while trying to track down a Vakil report. I've never been able to purchase personal copies of the A Descriptive List of the Vakil Reports Addressed to the Rulers of Jaipur books, and I've lost track of how many times I've checked the series out at my home library. Metzger's catalogue isn't complete, but it's a great start.
