Papers software for Macintosh computers is an interface for searching and reading academic papers. When configuring this software, enter the following urls: 

• Authentication: http://proxy.lib.duke.edu/login?url=
• Library Proxy: http://proxy.lib.duke.edu/login?url=%@

Please note that Duke's EZProxy setup doesn't automatically proxy everything, only those sites that have been specified in Duke's EZProxy configurations.  This should work for most Duke resources, but won't for users from other institutions.
