Also the site’s Annotated Bibliography Yonathan Ayalew Arjun Duggaraju information can be relayed easily to a lay audience such as a general consumer or house owner. Spangenberg, Karl Rudolph. Vacuum Tubes. New York, NY: McGraw-Hill, 1948. Print. This source is a source I found through the library under journals. It seems a little outdated but it provides good background on vacuum tubes. It starts out by describing what vacuum tubes are found in and how they are used. Understanding the background is critical because to present on vacuum tubes, we need to understand how they work. This might be the hardest resource to read through but provides a lot of good information. Taylor, L.S. “A Thumbnail History of Electronics: Vacuum Tubes: Edison, Fleming, De Forest, Coolidge, Schottky, Langmuir.” University of Maryland, Web. n.d. 24 April 2011. http://www.ece.umd.edu/~taylor/Electrons3.htm This source comes from the Electrical Engineering department at the University of Maryland. It provides information on some of the most key players in the advancement of vacuum tube technology such as Edison, Fleming De Forest, Coolidge, Schottky, and Langmuir.
