Information that tells you that a resource is a journal article may include:
If you think it is a journal article, but can't find the information you need to be sure, sometimes you need to look around a bit, this information is sometimes at the bottom of a page on a journal article or even at the end of the article. Have a look to see if there is a PDF version of it to look at as they usually show you the original version with all the relevant information (and page numbers if it has them). Better yet, look on Library search to see if we have it in the Library.
The interactive activity below highlights key clues to identify whether a resource is a journal article, focusing on web search results, documents, and Library Search results.
