"Along with books, The Online Books Page is also now listing major archives of serials (such as magazines, published journals, and newspapers) (...). Serials can be at least as important as books in library research. Serials are often the first places that new research and scholarship appear. They are sources for firsthand accounts of contemporary events and commentary. They are also often the first (and sometimes the only) place that quality literature appears. (For those who might still quibble about serials being listed on a 'books page', back issues of serials are often bound and reissued as hardbound 'books'.)" (excerpt from the 1998 website) In 1999, after graduating from Carnegie Mellon with a Ph.D. in computer science, John Mark moved to work as a digital library planner and researcher at the University of Pennsylvania Library. He also moved The Online Books Page there, kept it as clear and simple, and went on expanding it. The Online Books Page offered links to 12,000 ebooks in 1999, 20,000 ebooks in 2003 (including 4,000 ebooks published by women), 25,000 ebooks in 2006, and 30,000 ebooks in 2008. The books "have been authored, placed online, and hosted by a wide variety of individuals and groups throughout the world", with 7,000 books from Project Gutenberg. The FAQ lists copyright information about most countries in the world, with links to further reading. 1994: SOME PUBLISHERS GET BOLD AND GO DIGITAL = [Overview] Some bold publishers decided to use the web as a marketing tool. In the U.S., NAP (National Academy Press) was the first publisher in 1994 to post the full text of some books, for free, with the authors' consent. NAP was followed by MIT Press in 1995. Michael Hart, founder of Project Gutenberg, wrote in 1997: "As university publishers struggle to find the right business model for offering scholarly documents online, some early innovators are finding that making a monograph available electronically can boost sales of hard copies" (excerpt from the Project Gutenberg Newsletter of October 1997). Digital publishing became mainstream in 1997. Digitization accelerated the publication process. Editors, designers and other contributors could all work at the same time on the same book. For educational, academic and scientific publications, digital publishing was a cheaper solution than print books, with regular updates to include the latest information. = Publishers get bold Some publishers decided to use the web as a marketing tool.
