In Carlin’s archives, by contrast, the jokes were “mainly scraps of paper organized into Ziploc baggies then put into a folder by topic.”

Instead, Rivers is donating the extensive collection to the National Comedy Center, the high-tech museum in Jamestown, N.Y., joining the archives of A-list comics like George Carlin and Carl Reiner. The fact that the jokes will be accessible is only one of the reasons for Melissa Rivers’s decision.

To comedians, “material”—their jokes and stories—has always been precious, worthy of protecting and preserving.

Nevertheless, Heftel says, the notes tend to stick close to the major themes of Carlin’s work: “big ideas, the minutia of everyday life, and then language.”

Over time, Carlin formalized that system: paper scraps with words or phrases would each receive a category, usually noted in a different color at the top of the paper, and then periodically those scraps would be gathered into plastic bags by category, and then those bags would go into file folders. Though he would later begin using a computer to keep track of those ideas, the basic principle of find-ability remained. “That’s how he built this collection of independent ideas that he was able to cross-reference and start to build larger routines from,” Heftel explains.

Seeing how his system worked is enough to inspire anyone not to let thoughts go to waste, notes Carlin estate archivist Logan Heftel. “A good idea,” Heftel says Carlin learned early, “is not of any use if you can’t find it.”

Now that they are part of comedy history, it can be hard to imagine George Carlin’s most famous routines as anything but finished products. Whether the infamous “Seven Words” from his album Class Clown (released exactly 45 years ago Friday) or the monologues from his hosting of the first-ever episode of Saturday Night Live (which returns for its 43rd season this Saturday), these routines can seem to have sprung fully formed from his mind. But there’s plenty of physical evidence to the contrary.

George Carlin’s file folders These filing systems are all analog examples, but one of my heroes, George Carlin, embraced an analog/digital system: I take a lot of single-page notes, little memo pad notes. I make a lot of notes on those things. For when I’m not near a little memo pad, I have a digital recorder… When I harvest the pieces of paper and I go through them and sort them, the one lucky thing I got in my genetic package was a great methodical left brain. I have a very orderly mind that wants to classify and index things and label them and store them according to that. I had a boss in radio when I was 18 years old, and my boss told me to write down every idea I get even if I can’t use it at the time, and then file it away and have a system for filing it away—because a good idea is of no use to you unless you can find it….[In my filing system there are files for all kinds of subjects] but then there are subfiles. Everything has subfiles….It’s like nested boxes, like the Russian dolls—it’s just folders within folders within folders. But I know how to navigate it very well, and I’m a Macintosh a guy and so Spotlight helps me a lot. I just get on Spotlight and say, let’s see, if I say “asshole” and “minister,” I then can find what I want find. “A lot of this,” Carlin said, “is discovery. A lot of things are lying around waiting to be discovered and that’s our job is to just notice them and bring them to life.”
