<b>Which are the influential publications in the Web of Science subject categories over a long period of time? CRExplorer software used for big-data analyses in bibliometrics</b>
What are the landmark papers in scientific disciplines? 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 published results for their 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 during the citing years to the top-‰ in their subject area. The results for three subject categories "Information Science & 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 <a href="http://crexplorer.net">crexplorer.net</a>.
