\end{quote}  With the introduction of exactingly searchable databases, the playing field is indeed leveling for access and awareness of all tiers of journals, splashy-high-impact factor or otherwise. This naturally leads to faster and more efficient scientific endeavors. (Imagine getting \href{https://www.authorea.com/users/3/articles/10564/_show_article}{even closer}, accessing new developments and discoveries in near-real-time. If you think the rate of progress in science is dizzying \textit{now}....)  Not mentioned, however, is the fact that fields have grown more specialized, and publishers have responded by producing more specialty-specific journals. This may in part account for the increased share of non-elite citations: the publication of a groundbreaking article in a lower impact specialty journal will become a necessary citation in many subsequent papers in that and related fields. Another interesting point to consider in future studies is how open access journals measure up in citation rate. It has also been documented that high impact, elite journals have higher rates of retraction\cite{Fang_2011}. retraction \cite{Fang_2011}.  Do the high impact works from non-elite journals show comparable rates of retraction? Given their high impact, many of the same explanations high impact journals give for higher retraction rates should still apply (i.e. increased exposure and thus increased scrutiny). One more thing. Look at this graph:
