Some examples:
Scientific journal articles reporting experimental research results
Proceedings of Meetings, Conferences and Symposia.
Technical reports

In science, secondary sources are those which simplify the process of finding and evaluating the primary literature. They tend to be works which repackage, reorganize, reinterpret, summarise, index or otherwise "add value" to the new information reported in the primary literature.
Some Definitions:
Describe, interpret, analyze and evaluate the primary sources.
Comment on and discuss the evidence provided by primary sources.
Are works which are one or more steps removed from the event or information they refer to, being written after the fact with the benefit of hindsight.
Some examples:
Dictionaries and encyclopedias
Handbooks and data compilations
Journal articles, particularly in disciplines other than science (may also be primary)
Monographs (other than fiction and autobiography)
Newspaper and popular magazine articles (may also be primary)
Review articles and literature reviews
Textbooks

A primary source contains first-hand reporting of an historical event. The individual witnessed the event and records it at that time or somewhat later. When searching the online catalog try one of these keywords: autobiographies, correspondence, diaries, letters, memoirs, or personal narratives. Remember to add the research topic to the search, for example "suffrage."
Primary sources may include:
A secondary source is removed in time from the historical event and is not a first-hand report of it. It might be a commentary on the event, an analysis, research, or a review of it.
Secondary sources may include:
The description of Primary Sources at Yale may help to provide insight into the different possible types available for research. Please check Quinnipiac Library resources and the Web.
