So how many scholarly papers are on the Web, anyway? “Using statistical methods, [Lee] Giles and [Madian] Khabsa estimated that at least 114 million English-language scholarly documents are accessible on the Web, of which Google Scholar has nearly 100 million. They estimate that at least 27 million (24 percent) are freely available since they do not require a subscription or payment of any kind. The estimates are limited to English documents only.” http://news.psu.edu/story/329490/2014/10/09/research/how-many-scholarly-pape... -- This message has been scanned for viruses and dangerous content by MailScanner, and is believed to be clean.
