Article databases are tools you can use to find articles on a variety of topics. Some databases are interdisciplinary (they cover multiple subjects/topics) and some are subject-specific (they specialize in providing articles on a single subject). Use the tabs below to explore different kinds of databases, and use the Tips section to learn how to search in databases.
Note: If you find an article in Google Scholar and it doesn't link you back to the OT Library, you can submit a request to get the article from another library for free.
Exploring a topic related to your major? Try a subject-specific database.

A DOI, or Digital Object Identifier, is a unique identifier assigned to a specific article or document. It consists of numbers, letters, and symbols. For example:
10.3390/en15217997
DOIs can be written as URLs as well:
https://doi.org/10.3390/en15217997
Because the DOI is unique to the item it's assigned to, it can be used to look up and access articles. Some citation styles require the inclusion of DOIs when one is available for an item. You can also use a DOI to look up an article and see if full text is available for free on the internet from the DOI website.
