  The scientific community is facing one of its greatest challenges in solving
a global health problem: COVID-19 pandemic. This situation has generated an
unprecedented volume of publications. What is the volume, in terms of
publications, of research 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 different databases (Dimensions, Web of Science Core Collection,
Scopus-Elsevier, Pubmed and eight repositories). In relation to the results
obtained, Dimensions indexes a total of 9435 publications (69% with peer review
and 2677 preprints) well above Scopus (1568) and WoS (718). This is a classic
biliometric phenomenon of exponential growth (R2 = 0.92). The global growth
rate is 500 publications and the production doubles every 15 days. In the case
of Pubmed the weekly growth is around 1000 publications. Of the eight
repositories analysed, Pubmed Central, Medrxiv and SSRN are the leaders.
Despite their enormous contribution, the journals continue to be the core of
scientific communication. Finally, it has been established that three out of
every four publications on the COVID-19 are available in open access. The
information explosion demands a serious and coordinated response from
information professionals, which places us at the centre of the information
pandemic.
