Theodore Pollack, Senior Law Librarian at our public access law library writes: “Here is an interesting feature for Google Scholar regarding attempting to locate journal articles that are not easily available in Westlaw, Lexis, or HeinOnline. If you set the preferences in Google Scholar to libraries that you have access to, Scholar is supposed to inform if the article is available online thorough a digital subscription.”
