Throughout an unusually sunny Fall in 1970, hundreds of students and faculty at Syracuse University sat one at a time before a printing computer terminal (similar to an electric typewriter) connected to an IBM 360 mainframe located across campus in New York state. Almost none of them had ever used a computer before, let alone a computer-based information retrieval system. Their hands trembled as they touched the keyboard; several later reported that they had been afraid of breaking the entire system as they typed.
