Check:
- the database record for the article, which sometimes indicates whether a journal is peer reviewed
- the journal website, esp. under About Us or Information for Authors
- Ulrichsweb, a database of information about journals, and look for the Refereed symbol next to the journal title
Results in the library search box will indicate whether online access is available.
Click on the Find Full Text @ UNH link in the database record to see how to get a copy of the article: whether online, in print or from another library.
If the UNH Library doesn't have the article you want, request it through Interlibrary Loan.
