"Non-profit electronic archiving service provider Portico, US, has announced that more than 10 million journal articles are preserved within the Portico archive. Launched in 2005 with support from JSTOR, The Andrew W. Mellon Foundation, Ithaka, and the Library of Congress, Portico provides a permanent archive of scholarly literature published in electronic form.
The Portico archive is supported by both publishers and libraries and is increasingly central to the digital preservation and permanent access strategies of institutions around the world.
The growth of the archive underscores the importance of preservation archives in facilitating a secure transition from print to electronic collections. At the close of 2008, 68 publishers producing journals and e-books on behalf of hundreds of scholarly societies participated in Portico and have entrusted over 8,200 journal titles and 4,600 e-books to the archive. Libraries from the global community have been equally supportive of Portico with nearly 500 current participants from 13 countries.
