You can search through the CSN Libraries Find Articles page to search for peer-reviewed research on your topic. If you need to find out whether a source is peer-reviewed or not? Use Ulrichsweb to search by journal title name to see if your material has been through a rigorous peer-reviewed process.
On the results screen from any database choose the types of material you want. Including availability, "peer-reviewed" articles, publication dates, and subject areas you want to include (each database will look different, but the limiters on the left side of databases remains the same):
For all kinds of tricky citations, Google Scholar can be your saving grace. If you have just a partial citation (like an author, date, and subject) use the Advanced Search in Google Scholar to piece together the missing information.
Many universities are now publishing theses and dissertations in institutional repositories, which are freely available on the web and searchable via Google Scholar. You may be able to find recent dissertations on your research subject online!
Conferences and associations also sometimes publish their proceedings and publications freely online, so they may be accessible through Google Scholar.
Google Scholar is a go-to source for academic librarians, and you can use it too!
