ECE: Summer Internship Programs: Free Scholarly Resources

Accessing Scholarly Resources

UC San Diego students, faculty, and staff have access to electronic scholarly resources that are unavailable to most students, researchers and others who do not have access through a university library.

Below are some ways to access scholarly sources (particularly journal articles) that may be freely available. You can also email the authors themselves, who may be able to send you a copy of the paper. Every paper should have a "corresponding author" to handle queries from readers. There's no guarantee the author will respond quickly (or at all), but it is worth a try. If the author is affiliated with a university, check their department/lab website, as some also post copies of their articles in their publications list.

Finding Free Scholarly Resources

Below are databases and search engines to help you access scholarly books and articles that are "open access," freely available to the public without paywalls.
