The BibCharts were a monthly overview created by the ZBW - Leibniz Information Center for Economics (zbw.eu) since 2011, showing how many fans on Facebook, followers on Twitter or subscribers on Instagram libraries and information centers have.
Due to changes in the API guidelines, especially for Facebook and Instagram, it is effectively no longer possible to retrieve this data in an automated way that complies with the guidelines. For this reason, BibCharts was discontinued at the end of 2022. A big thank you to our loyal users:inside the past years!
