Wizards (chapter one):
> Licklider was no exception to the rule that people didn’t spend a long time at ARPA. But by the time he left in 1964, he had succeeded in shifting the agency’s emphasis in computing R&D from a command systems laboratory playing out war-game scenarios to advanced research in time-sharing systems, computer graphics, and improved computer languages. The name of the office, Command and Control Research, had changed to reflect that shift, becoming the Information Processing Techniques Office.

> Taylor told the ARPA director he needed to discuss funding for a networking experiment he had in mind. Herzfeld had talked about networking with Taylor a bit already, so the idea wasn’t new to him. He had also visited Taylor’s office, where he witnessed the annoying exercise of logging on to three different computers. And a few years earlier he had even fallen under the spell of Licklider himself when he attended Lick’s lectures on interactive computing.
> Taylor gave his boss a quick briefing: IPTO contractors, most of whom were at research universities, were beginning to request more and more computer resources. Every principal investigator, it seemed, wanted his own computer. Not only was there an obvious duplication of effort across the research community, but it was getting damned expensive. Computers weren’t small and they weren’t cheap. Why not try tying them all together? By building a system of electronic links between machines, researchers doing similar work in different parts of the country could share resources and results more easily. Instead of spreading a half dozen expensive mainframes across the country devoted to supporting advanced graphics research, ARPA could concentrate resources in one or two places and build a way for everyone to get at them. One university might concentrate on one thing, another research center could be funded to concentrate on something else, but regardless of where you were physically located, you would have access to it all. He suggested that ARPA fund a small test network, starting with, say, four nodes and building up to a dozen or so.

From chapter two of Wizards:
> Roberts also learned from Scantlebury, for the first time, of the work that had been done by Paul Baran at RAND a few years earlier. When Roberts returned to Washington, he found the RAND reports, which had actually been collecting dust in the Information Processing Techniques Office for months, and studied them. Roberts was designing this experimental network not with survivable communications as his main—or even secondary—concern. Nuclear war scenarios, and command and control issues, weren’t high on Roberts’s agenda. But Baran’s insights into data communications intrigued him nonetheless, and in early 1968 he met with Baran. After that, Baran became something of an informal consultant to the group Roberts assembled to design the network. […]
