Consisting of quotes, economic statistics, jokes, and anecdotes, they became the core of Ronald Reagan’s traveling research files.

"You can talk to any number of President Reagan's speechwriters over the years, and when they might hand him a speech, the speeches would come back with a quote, or an expression or a joke that they hadn't seen before," John Heubusch, executive director of the Reagan Library, told CBS News' Mo Rocca.

Ronald Reagan notecard

"If the Reagans' home in Palisades (Calif.) were burning," Brinkley says, "this would be one of the things Reagan would immediately drag out of the house. He carried them with him all over like a carpenter brings their tools. These were the tools for his trade."

Protect it at all costs. As the historian Douglas Brinkley said about Ronald Reagan’s collection of notecards: “If the Reagans’ home in Palisades were burning, this would be one of the things Reagan would immediately drag out of the house. He carried them with him all over like a carpenter brings their tools. These were the tools for his trade.”

Ronald Reagan actually kept quotes on a similar notecard system.

Ronald Reagan also kept a similar system that apparently very few people knew about until he died. In his system, he used 3×5 notecards and kept them in a photo binder by theme. These note cards–which were mostly filled with quotes–have actually been turned into a book edited by the historian Douglas Brinkley. These were not only responsible for many of his speeches as president, but before office Reagan delivered hundreds of talks as part of his role at General Electric. There are about 50 years of practical wisdom in these cards. Far more than anything I’ve assembled–whatever you think of the guy. I highly recommend at least looking at it.
