Summer queries?

There won’t be many posts from me for the next few months, so I thought I might invite others to submit queries connected to their research. I have in mind things like “Does anyone know what this is a reference to?” or “Does anyone know where I can get an electronic copy of this rare book?” or “Does anyone know whether anyone is working on this specific topic?”

You cannot directly post to the blog — you have to send me an email <>. An advantage of this procedure is that I will post only queries that strike me as worthy, meaning that no one should worry about posting a stupid question.  And don’t worry about sending me a stupid question — I’m used to it.

Queries in other major languages are welcomed.
