Each section includes tables with publication statistics and charts, which can be downloaded in various formats. The charts are interactive so that observing facilities can be included or omitted as needed.

While all APEX and ALMA data papers are recorded in the telbib database, only those that use ESO data are counted in the statistics. Articles using data from visitor instruments for which ESO schedules observing time are considered ESO data papers, but national and hosted facilities are not included unless their observations are combined with data from ESO facilities.

Weekly updates ensure that the data are up to date. Current year information becomes available as of July. As of March, the previous year’s statistics can be considered to be complete. To enable easy re-use, the work is licensed under a Creative Commons Attribution (CC-BY) 4.0 license. 

Telbib is developed, maintained, and curated by the ESO Librarians. Statistics derived from telbib help ESO’s management to evaluate research output and performance. In addition to the Basic ESO PubStats, a variety of other reports and visualisations are available on the web (e.g., interactive graphs, overview, reports) and on request.
