I'm responsible for recommending purchases of research level monographs to my university library. My job would be vastly simplified if I could find a website (say) that made it easy to scan a list of recent publications of that sort. At present I find I must visit the websites of dozens of publishers.
I'm open to any suggestions, but let me mention some resources which I already use, but only with effort and partial success:
1) The library catalogs of other institutions. -- Generally by the time another college or university has a book cataloged the book isn't current. Also searching by publication date, to get current books, seems impossible unless I'm already searching under fairly a narrow subject heading such as "algebraic topology," but that would have me making many dozen of searches.
2) Amazon (or the like). Great for currency, but not easy to narrow the search to research level books, and broaden the search to cover all of university level mathematics.
3) Notices of the AMS Certainly current and useful for AMS publications, but the advertisements would bias me towards big publishers and the particular books they choose to push.
Thanks in advance for whichever way anyone points me. If nothing of the sort exists, feel free to suggests ways to create, or induce the creation, of such a web resource.
