The Proxy Bookmarklet lets you reload a web page through the U-M Library's proxy server. If the site you are visiting is one that the library has a subscription for, and you're presently off-campus or on the University's wireless network, you can get immediate access to the resource once you've logged in with your uniqname and UMICH password and have been verified to have a valid library account.
Desktop and Laptop Users: Get the MLibrary Proxy bookmarklet.
iPhone/iPad Users: Get the MLibrary Proxy Bookmarklet for iPhone and iPad.
