The scientific community is facing one of its greatest challenges in solving a global health problem: the Covid-19 pandemic. This situation has generated an unprecedented volume of publications. What is the volume of scientific publications on Covid-19? The general objective of this research work is to obtain a global vision of the daily growth of scientific production on Covid-19 in various databases (Dimensions, Web of Science Core Collection, Scopus, PubMed, and eight repositories). In relation to the results obtained, Dimensions indexes a total of 9,435 publications (69% with peer review and 2,677 preprints) well above Scopus (1,568) and WoS (718). This is a classic bibliometric phenomenon of exponential growth (R2 = 0.92). The daily global growth rate is 500 publications and the production doubles every 15 days. In the case of PubMed the weekly growth is around 1,000 publications. Of the eight repositories studied, PubMed Central, medRxiv and SSRN are the leaders, but despite their contribution, journals continue to be the core of scientific communication. Finally, it has been established that three of every four publications on the Covid-19 are available in open access. The information explosion which places us, information professionals, at the centre of the information pandemic demands a serious and coordinated response.
