The resources we’d marshaled for the original story all fit into the new model. Beyond that, however, for this program, we have utilized a significant number of clips from outside sources. In fact, this program strongly exemplifies the Fair Use doctrine of US copyright law. To quote directly from the US Copyright Office:
The realm of Fair Use has lured many in; some have emerged with unclean hands. Rather than a blanket approval for the wholesale ripping off of the work of others, this seemingly simple idea has severe limits . . . but they are vague. This infuriates those attempting to find their way through the thicket of copyright and fair use while keeping to the straight & narrow, and it makes some lawyers a bit wealthier than perhaps good public policy might prefer.
We even bought her book.
The more important question relates to how extensively one should rely upon outside sources in the first place. We feel that such practice ought not to be encouraged. This program, “You Want to Build a Railroad, Do You?”, is a one-off in its need for this much borrowed content.
