The Waiver Wire screen (League Menu >> Transactions section >> Waiver Wire) lists players who are currently on waivers:

To claim a player off of waivers, right-click on the player name and select Claim Player. See Waivers for more information about the concept of waivers, the claim process, and so on. Players who are on waivers will be displayed here until their waiver period has ended. If waivers have been disabled in the Roster Rules section of the Rules page, then this screen will not be available.

On this page, you can take advantage of OOTP's Views, Filters, and many of the Common Drop-Downs. Review those sections to get a better understanding of how to manipulate the data on this screen to suit your needs.
