ERIC has many peer-reviewed articles available as full-text. To find them, do a search and then click on the checkboxes at the top of the result screen. Set it to "peer reviewed" and "full text" and hit the "search" button again to filter the results.
This site allows you to search over 22 million records. While it includes content from PubMed Central, it is more comprehensive in scope. Some material will be available in full-text access and some will be citation information only. Check our holdings through Full Text Finder to see if we have access to the full text through the library's collections.
