Search the Copyright Clearance Center
Search the U.S. Copyright Office Catalog for, "Works registered and documents recorded by the U.S. Copyright Office since January 1, 1978." However, it is not necessary to register with the copyright office therefore not all copyright protected works will be included in their catalog.
EBSCO is not the copyright holder on the articles included in their databases. Their guideline mirrors that of fair use: "Generally, it is acceptable to use one article per issue and to put it on electronic reserve for only one semester. Using more than one article per issue, or using an article for more than one semester, would require permission from the publisher."
An example of the copyright notice on articles in EBSCO databases:
Taylor & Francis
"We are the owner or the licensee of all copyright, trademarks, design rights, database rights, confidential information, or any other intellectual property rights (together the "Intellectual Property") in the Site, the content and the Materials."
