Now that you have a Topic, you need to search for Sources. Use your Topic to define the Keywords you will use to find Books and Articles.
Think of new Keywords that are related to your Topic.
Euclid, Euclidean Geometry, Geometry, Elements; Euclid's Elements
Rhind Papyrus; Egyptian Number System; Egyptian Numerals; Numerical Notation; Number Notation
Since you are will be writing about a historical topic or biography, include keywords to help limit to those types of articles, e.g.:
History; History of Mathematics; Mathematics History; Ancient Mathematics; Biography
Try different Keyword combinations when searching.
Use AND to link terms together and narrow your search:
Mathematics AND History
Use OR to link terms together and broaden your search:
Number System OR Numerals AND Egypt
Use the Asterisk * (truncation) to search for different forms of a word:
Math* searches for Math, Mathematics and Mathematicians
Use Quotation Marks to keep Phrases together:
Once you've started finding articles on your topic (see the Finding Articles tab on where and how to search), look at the subject terms to get ideas of other keywords to search under. When you read the abstract, make note of additional terms to look up.
Note: If you prepare a presentation (ppt, prezi etc), it should include informative visuals with citations:
