Using the internet

In Chris Nolan's presentation I learned that I could use Google Scholar to find more scholarly sources when researching. I also was interested in the fact that 70% or more of the internet is invisible in journals or databases. I had wondered exactly how Google and Yahoo ranked their entries in search engines. Google uses keywords in the title, in the article, and number of links from other sites to rate which webpages come up first in a search. Google was also the first large database to use an automated bot to search web pages.
