\begin{tablenotes}\footnotesize\item Institutions: number with at least two hundred works in the period; Top-10/50/100: fractional share of the largest listed institutions relative to the listed institutions, not to all works. The row `both periods' counts the institutions present in both lists (its work columns are their baseline totals); the Spearman rank correlation of their fractional counts across periods is 0.893.\end{tablenotes}
