Secondary Sources are secondhand sources. They were created by historians who drew their information from primary sources. Secondary sources include scholarly journal articles, books, and credible web sites.
Dissertations & Theses can be used as secondary sources and in some cases it may be easier to find a dissertation or thesis that addresses your specific topic.
