Today, analysis of citations has diffused into the mainstream use of academicians, thanks to the analytics tools incorporated into academic search engines and indices.
As early as 2007, I have advocated for the use of these tools, but back then, the applicability of the idea was very limited due to lack of quality data. The references of publications were not available, and to extract them automatically one needed good working OCR tools, as well as a lot of manual cleaning and editing. In short, it was a cumbersome enterprise.
Some of my early publications are devoted to the analysis of Arts & Humanities publication trends and the specifics of citation tradition inside humanities. We have prepared a website displaying the position and environment of every individual journal in A&HCI (2008) based on their similarities in citation patterns.
The journal Leonardo was an in-depth study, a representative sample, and we generated an animation to show how its citation network changed over time, and what we can conclude from these changes:
Leonardo's Citation Environment (based on the references that appeared in Leonardo)
Leonardo's Knowledge Base (papers & journals that refer to articles that appeared in Leonardo).
