Don’t take isolated notes, connect them! Vannevar Bush on building a self-organizing network of knowledge
In 1945, Vannevar Bush presented his concept of a self-organizing personal knowledge network by linking informational units with each other. This concept, that would later be known as the Hypertext concept or Hypertext theory, provides the theoretical base of the personal knowledge management system presented in the short series on that topic. This is the first of three parts of that series.
Boost your research with a smart personal knowledge management system
My next posts will be a short series about personal knowledge management and how it can be integrated as a holistic system into our overall research workflow. The system is based on the Hypertext Theory and the Zettelkasten method, and its core element is the personal note-taking process. We go step by step through all parts and see, how we can practically implement them into our daily research work.
