It's not easy being a documentary filmmaker. Getting the pictures made is hard; finding distribution can be even harder.

Enter Snagfilms.com. It's a Web site that offers hundreds of documentaries for free viewing. You can also "snag" the movies, embedding them in your blog, social-media page or Web site.

This is not YouTube material. These are full-length films from PBS, National Geographic, independent filmmakers and others. (For those of you interested in such things, each movie contains 90 seconds per hour of advertising. The filmmakers get a cut.)

This week, to honor the 9/11 anniversary, Snagfilms is offering a slate of six 9/11-themed feature films (with no advertising).

The most prominent: 7 Days in September, which recreates the experience of New Yorkers in the week following the attacks. It's a moving portrait, especially for anyone who lived through the events.
