Background sources are written for a general audience and are intended to give an overview of a topic, fill gaps in the reader’s knowledge, and provide context for deeper understanding. Examples include Wikipedia, introductory textbooks, and reference works such as encyclopedias, dictionaries, and handbooks.
When working on a new research topic, it is often helpful to begin with these three questions,
· What research question you want to answer in this paper?
· How to narrow down to specific topic?
· What are the available USEFUL resources for your topic?
Beginning with reading a basic overview of the subject is often a good start.
Encyclopedias and dictionaries provide such overviews to help you familiarize with relevant vocabulary and to provide useful suggestions for further readings.

There are two major call number systems used in the libraries: the Dewey Decimal and Library of Congress classification schemes. The first line of a call number, as it appears on a physical item, is a broad subject classification. The subsequent lines are combinations of letters and numbers that organize items into narrower, related categories.
|Library of Congress||Dewey Decimal|
615 Whole number
|573.3 Whole number, followed by decimal
|C518 Alphabetically, then decimals
(may be followed by another letter)
|.W932A Alphabetically, then decimals|
|2018 Publication Date, shelves chronologically||e.g., 573.3 W932A shelves before 573.3 W94A|
