  What are the landmark papers in scientific disciplines? On whose shoulders
does research in these fields stand? Which papers are indispensable for
scientific progress? These are typical questions which are not only of interest
for researchers (who frequently know the answers - or guess to know them), but
also for the interested general public. Citation counts can be used to identify
very useful papers, since they reflect the wisdom of the crowd; in this case,
the scientists using the published results for their own research. In this
study, we identified with recently developed methods for the program CRExplorer
landmark publications in nearly all Web of Science subject categories (WoSSCs).
These are publications which belong more frequently than other publications
across the citing years to the top-per mill in their subject category. The
results for three subject categories "Information Science and Library Science",
"Computer Science, Information Systems", and "Computer Science, Software
Engineering" are exemplarily discussed in more detail. The results for the
other WoSSCs can be found online at http://crexplorer.net.
