Over 6 months ago, I published a paper in a journal that is on MathSciNet's journal list, and has been for a long time. It's not the Annals, but it's a solid and reputable journal. My paper is in applied mathematics (applied to a different topic in the real world), but clearly of a mathematical nature. The primary interest is mathematics, more so than the results we obtain about the topic at hand.
So far, this paper has not been indexed on MathSciNet. Papers I have published after it have been indexed. Other papers from the exact volume of the journal have been indexed. In fact, other papers from the same volume of the same journal and the same journal subtopic as my paper have been indexed.
I've emailed them twice about this at mathrev@ams. Twice I have received the same response, "Thank you for your message. The paper you mentioned has been forwarded to the editors of Mathematical Reviews / MathSciNet for consideration." I have received this response 1 month and 4 months ago.
I question why and how Mathematical Reviews can be making editorial decisions on what "counts" for indexing or reviewing. Surely they do not have the time and resources to do a proper peer review of every paper. (Side note: every paper of mine that has been "reviewed" has just featured an exact quote of the paper abstract as its "review.") The paper has been reviewed and published in one of their listed mathematics journals, the AMS does have categories for applied mathematics that it includes, and the paper is clearly mathematical in nature (unlike say a philosophical paper appearing in a mathematical journal). Part of me feels like taking this as a slight, though I'll seek an alternative explanation.
Has anyone else experienced this and what should I do? In my environment, it's rather important to have papers listed on MathSciNet, rather than arXiv, Google Scholar, etc.
