Yes, there is WiFi (wireless internet) in the Library that both guests and Purchase affiliates can use. Both are managed by CTS.   There are two WiFi networks with the following names:

Please see our Wi-Fi Heat Map for coverage areas in different buildings.

PurchaseWiFi:  Students, faculty, and staff should choose the “PurchaseWiFi” network. The username is your Purchase email username (firstname.lastname WITHOUT the @purchase.edu) and the password is your Purchase email password.  You should only have to enter your username and password once to have access.

PurchaseGuest: Guests and visitors to campus should choose the “PurchaseGuest” network.  The password changes at least twice a year.  You can ask a library employee at the Circulation or Reference desks for the current password or view the Guest Wifi page.

Note that PurchaseGuest network is limited; it enables you to view webpages and use most apps, but not to use high-bandwidth services like Skype, video streaming, etc. On mobile devices, the guest network may also prevent off-campus email accounts from refreshing (such as Gmail or the Mac OS mail app). To get around this, access your email via a web browser, rather than an app or mail client.
