14 shown of 14 papers with a leaderboard row on this dataset's benchmarks, newest first. The archive's own "papers using this dataset" list was never published, so this is the benchmark-backed subset; the archive's count for this dataset is 66. The Syntology column is from Syntology's graph (read 2026-09-24), stated per sample; it is not part of any archive number.
