Dear Prof. Preisendanz,
You are correct, there is such a website. It is the Cologne one, most commonly associated with the Monier-Williams dictionary.
Then, in the "Dictionary" box where the page defaults to "MW", simply change the code there, either by clicking with the drop-down menu or by typing. The desired Pune dictionary is accessed with the code "PD". (Two editions of Apte are also available, although my preferred digital interface for that remains the trickier-to-use Chicago website, which nevertheless allows not only a
single-entry view but also a
page view.)
You'll notice that the search box even features auto-completion while one types. I think you'll agree, this already useful resource has now become significantly more powerful. For whatever reason, however, awareness of the new interface remains low. I think I will forward our exchange on to the Indology list, if you don't mind. I read it daily and also just now searched the archive, but I haven't yet seen any trace of a proper announcement.
With kind regards,
Tyler
