These research databases will find mathematical journal articles, conference proceedings papers, and monograph series (like Lecture Notes). They will also find some single books (like textbooks), but not all.
See below for tips on searching with MathSciNet. You can also email me for help at any time.
Unlike the three tools above, arXiV includes preprints posted by the authors themselves, without a peer-review process. It is now widely used in areas like computer science.
If you are not finding good results with MathSciNet, you can adjust the default search options. In addition to the article titles, you can search the review summary (similar to an abstract, usually written by another mathematician) by choosing 'review text' as the search parameter. This will find more articles than just searching the title alone.
Every item in MathSciNet is also categorized into a field of math using the MSC Classification (you can browse or search the classification here).You can restrict your search to a broad field by entering a 2-digit code (for example, 13 for commutative algebra) or to a more narrow topic by entering a 3- or 5-digit code (for example, 13H05 for regular local rings). This can help if you are finding lots of results from areas you aren't interested in.
Looking for a journal to submit to? You can use MathSciNet's journal search to get data on potential targets, including their citation rates, subject areas of recent papers, top authors, and even a list of related journals. You can find more info on journal and author profiles here.
If an article has been published in a journal, we don't necessarily have the full text. Try these steps:
