Despite the -- or: due to the -- plethora of alternatives, I still haven't figured out which bibliographic database/search engine (Scopus, zbMATH, Google Scholar, ProQuest, EBSCO, JSTOR, etc.) offers the best coverage of OR/MS publications.
Also, assessing whether a paper presents what is considered the state of the art, cites highly relevant literature, a.s.o. are painful exercises.
So, my question is: What do you actually do when you browse the "interweb" for certain keywords, look up relevant publications in a specific (sub-)field, check for updated and/or improved results presented in a paper you've already read, etc.?
Do you use any of these databases/search engines listed above? If so, which -- and why, and how?
(Furthermore, if you are aware of a comparison/evaluation of databases/search engines from an OR/MS perspective, pointers are much appreciated.)
