A bibliography is a list of sources about a single topic. Each book listed in the bibliography is identified by its Author, Title, Publisher, Place of Publication, and Date of Publication. Articles from newspapers, journals and magazines include the title of articles, the authors, the journal or magazine, where it was published and the Volume, Issue Number, the Date of the Publication and the Pages the article appeared on. Each discipline has its own style for creating bibliography entries, e.g. MLA, APA.
When you write a paper the sources you refer to in your writing should appear in your Works Cited or References List.
Primary Source
Primary source is used to describe several different types of sources. In the Sciences, a primary source is an original research article. In the Humanities, a primary source could be the text of a novel or it could be an artifact like a map or a diary.
Scholarly Source
Scholarly sources are different from news sources because rather than reporting an event, scholarly sources ask and answer questions through some form of analysis. Scholarly sources are written by experts-- people who know a lot about their subject like professors and they also refer to other sources in a works cited/references list to show where their information came from originally.
