Eugene Garfield and Algorithmic Historiography: 
Co-Words, Co-Authors, and Journal Names

Annals of Library and Information Studies (forthcoming);

Algorithmic historiography was proposed by Eugene Garfield in collaboration
with Irving Sher in the 1960s, but further developed only recently into
HistCiteT with Alexander Pudovkin. As in history writing, HistCiteT
reconstructs by drawing intellectual lineages. In addition to cited
references, however, documents can be attributed a multitude of other
variables such as title words, keywords, journal names, author names, and
even full texts. New developments in multidimensional scaling (MDS) enable
us not only to visualize these patterns at each moment of time, but also to
animate them over time. Using title words, co-authors, and journal names in
Garfield's oeuvre, the method is demonstrated and further developed in this
paper (and in the animation at
<> ). The variety and
substantive content of the animation enables us to write, visualize, and
animate the author's intellectual history.
