SSRN, the Social Science Research Network, has recently launched a iPhone/iPad app.
SSRN is a repository of scholarly research for social sciences and humanities scholarship, including law. Many of our UW Law School professors have contributed scholarship to SSRN.
The SSRN app allows users to search over 260,000 research papers in the SSRN electronic library. The papers can be emailed or viewed right on the device.
