Looking for properly formatted BibTeX citations for articles or books can be tedious. I used to use the functionality from Google Scholar, but found that for many cases the BibTeX files are poorly formatted, are missing information, or even contain wrong information.
For mathematics papers, http://www.ams.org/mathscinet/ appears to be a reasonable alternative. But it is manually maintained and unfortunately a paid service (many universities have access).
Are there other similar databases, possibly for other fields of science?

For me, I do not use a single source, rather a combination of resources and techniques. Actually, there are a number of tools or resources you can use under the circumstances.
Please see here how you can do this in mendeley. You can even generate a .bib file in one go, which is rather nice. Other reference management tools like Papers, EndNote, or Zotero should have similar functionalities, I am not very sure.
