Founded in 1993 by John Mark Ockerbloom when he was a student at Carnegie Mellon University (in Pittsburgh, Pennsylvania, United States), the Online Books Page is "a website that facilitates access to books that are freely readable over the internet. It also aims to encourage the development of such online books, for the benefit and edification of all." John Mark Ockerbloom first maintained this page on the website of the School of Computer Science of Carnegie Mellon University. In 1999, he moved it to its present location at the University of Pennsylvania Library, where he is a digital library planner and researcher. The Online Books Page offered links to 12,000 books in 1999, 20,000 books in 2003 (including 4,000 books published by women), 25,000 books in 2006, 30,000 books in 2008, and 35,000 books in 2010. The books "have been authored, placed online, and hosted by a wide variety of individuals and groups throughout the world", with a number of books from Project Gutenberg. The FAQ gives copyright information for most countries in the world, with links to further reading. June 1993 > PDF and Acrobat Reader, launched by Adobe Adobe launched PDF (Portable Document Format) in June 1993, with Acrobat Reader (free, to read PDF documents) and Adobe Acrobat (for a fee, to create PDF documents). As the "veteran" format, PDF was perfected over the years as a global standard for distribution and viewing of information. It "lets you capture and view robust information from any application, on any computer system and share it with anyone around the world. Individuals, businesses, and government agencies everywhere trust and rely on Adobe PDF to communicate their ideas and vision" (excerpt from the website). Adobe Acrobat gave the tools to create and view PDF files, for a number of languages and platforms (Windows, Mac, Linux). Acrobat Reader was available for PDAs, beginning with the Palm Pilot (May 2001) and the Pocket PC (December 2001). Between 1993 and 2003, over 500 million copies of Acrobat Reader were downloaded worldwide. In 2003, Acrobat Reader was available in many languages and for many platforms (Windows, Mac, Linux, Palm OS, Pocket PC, Symbian OS, etc.), and approximately 10% of the documents on the internet were available in PDF.
