The importance of citations in scholarship
Citations are arguably one of the defining features of research communication. Linking the corpus of knowledge together, across time and space, they connect Einstein's work at the beginning of last century \cite{Einstein_1906} to researchers writing important physics research today \cite{Stanislavsky_2017}. This web of knowledge is immensely powerful for the analysis of ideas over time and for determining what might be important or not. If you imagine the scholarly corpus as a brain you can think of scholarly citations as its neural connections.
