Safari Books Online is a digital library providing on-demand subscription access to thousands of learning resources.
If you've ever connected to the Internet at one of the myriad Wi-Fi hotspots, such as in hotels, coffee shops, and airports, you know the drill. I'm talking about the mildly irritating two-step dance you must do before you can access the Internet, even when such access is free:
Join the Wi-Fi network. With your iPhone, this is usually as easy as a single tap on the network name when it appears, as there is no password requirement or other sort of restriction. At this point, while you have a Wi-Fi connection, you still have very limited, if any, Internet access.
Separately log in to the hotspot. To complete this step, you launch Safari and attempt to load any Web page; your request is intercepted, and a login page for the Wi-Fi network appears instead. You enter the data requested, such as a password or agreeing to a set of conditions, and then log in. If a password is required, it is typically provided to you by staff at the hotspot location.
