FRIDAY:

>> Get your read on at the DC Library Public Book Sale Friday & Saturday, from 10 a.m. to 3 p.m. at Martin Luther King, Jr. Memorial Library. You have a choice of paying $3 or less on Friday and getting access to the best selection, or $2 or less on Saturday for the leftovers. DCist has to work on Fridays, so we’re planning on showing up at 10 a.m. on the dot Saturday morning. And we’ll fight you for that 75 cent copy of Hitchhiker’s Guide to the Galaxy. Don’t test us.

>> The DC Shorts Film Festival kicks off its 2nd annual outing this weekend with a big opening night fiesta at Poste Brasserie starting at 6 p.m., followed by the first collection of screenings starting at 9 p.m. at E Street Cinema. A still from Kindness of Strangers, a short from D.C. director Claudia Myers, is above.

SATURDAY:

>> Hopefully the rain predicted for Saturday afternoon will hold off long enough for everyone to be able to enjoy this year’s Arts on Foot in Penn Quarter. If the official schedule looks a little overwhelming, might we suggest hopping aboard one of the guided tours offered this year.

>> We’ve given our collective thumbs up to comedian Todd Barry before, because he’s actually really funny. Plus anyone who’s done a guest voice for Aqua Teen Hunger Force pretty much has to be awesome. He’s at the DC Improv through Sunday.

SUNDAY:

>> Add the local club/rave scene to the list of those doing their best to bring relief to victims of Katrina. A laundry list of local promoters and partiers got together to put on FROM DC WITH LOVE with one of the better DJ line-ups seen at one party in a while, with all proceeds going to the Red Cross. At Nation, $15 before 8 p.m., $20 after.

>> Further evidence that the Swedes have really got this whole post-ironic rock thing down cold, Dungen brings its life-affirming retro-psych sound to Black Cat. With Mia Doi Todd. $13, 8:30 p.m.
