With the aim to improve visibility of repositories and good practices in their web publication we have extracted the following quantitative web indicators from the most important search engines. The methodology is similar, but not exactly the same, to those use in our other Rankings:

Size (S). Number of pages recovered from the four largest engines: Google, Yahoo, Live Search and Exalead.
Visibility (V). The total number of unique external links received (inlinks) by a site can be only confidently obtained from Yahoo Search and Exalead.
Rich Files (R). Only the number of text files in Acrobat format (.pdf) extracted from Google and Yahoo are considered.
Scholar (Sc). Using Google Scholar database we calculate the mean of the normalised total number of papers and those (recent papers) published between 2001 and 2008.

The four ranks were combined according to a formula where each one has a different weight but maintain the ratio 1:1 between activity (size sensu lato) and impact (visibility)

We ask for your cooperation. Any remark regarding addition or deletion of business schools is welcomed, as well as any comments or suggestions that will help us to improve the Ranking.
