An Overview of Portico: An Electronic Archiving Service

As scholars have become more reliant upon electronic scholarly journals, the long-term preservation of these resources has become a growing and increasingly urgent need. In 2002, JSTOR launched a project which has now become Portico, a new, not-for-profit electronic archiving service established to address the scholarly community's critical need for a reliable means to preserve scholarly e-journals. Portico is focused on preserving the intellectual content of e-journals through source file normalization and format migration. To date, seven publishers have agreed to deposit more than 3,000 journals in the archive, which will be sustained by contributions from publishers and libraries.
