Trail-Blazer
Bush's term for the
memex user who creates paths through knowledge that others can follow—a figure whose contribution is not new information but new
connections between existing information, making expert navigation visible and shareable.

tacit knowledge about which papers are foundational, which
findings are reliable, which connections are generative. Junior researchers could follow these trails, learning not only what to read but how experts navigate—the implicit logic guiding attention across a literature. Bush treated trail-blazing as professional contribution deserving recognition alongside original research. The concept anticipated link-making as creative work, influenced
