The tents are down. The authors have gone. And your book collection may be a bit bigger.

The seventh annual Tucson Festival of Books on the campus of the University of Arizona is history.

However, you can still view or revisit several panels from the ’15 festival — and archived video of all the festivals back to 2009 — at C-Span.org or tucne.ws/1xvHbDp

C-SPAN2’s BookTV and executive producer Peter Slen was at last week’s festival and the team added to its collection of free videos of past festivals — there are about 65 available.

The book festival offers “a great weekend of live programing,” says Cleve Corner, BookTV producer. The topics offered during the festival in the Gallagher Theater on the University of Arizona campus — national and international politics, history, current events and trends — are among the topics BookTV covers.

Book TV offers 48 hours of nonfiction book and author coverage every weekend, Corner says. BookTV broadcast about 15 hours of live coverage from this year’s Tucson book festival and some panels are being rebroadcast, he says.

The videos are available on-demand and on mobile devices. The cable and satellite industries fund C-SPAN (Cable/Satellite Public Affairs Network), says C-SPAN’s Laura Finch. No federal funds or advertising revenue support the public service network.

BookTV’s author panel from last weekend’s festival included:

  • Race & Politics
  • Narrative Non-fiction
  • Contributors to the Nation magazine
  • The Obama Administration
  • The Future of Politics
  • Charles Bowden’s Southwest
  • Concussions & the Future of Football

The archive includes viewer call-in segments that followed the panels.
