I have been serving for several years as a reviewer for both Mathematical Reviews (MathSciNet) and ZbMath.
Earlier this year, I received an invitation for a paper for MR which I already reviewed for ZbMath. I dug up my old review and submitted it to MathSciNet without giving it much thought.
But there seems to be a pattern emerging. I received an invitation from MR for two more papers I already reviewed for ZbMath.
So here are my questions:
- Do the editors of MR know/check who reviewed the paper for ZbMath in order to find suitable reviewers?
- What do I do about the double reviews?
My idea was to just refuse to write the reviews. But if the answer to the first question would be yes, then the editors know that I have a thorough review lying around. Just resubmitting this one would save a colleague from writing a new one.
