MARRA, MonicaMonicaMARRA2022-07-152022-07-152017978-1-61499-769-6http://hdl.handle.net/20.500.12386/32510This paper results to be the first, though absolutely initial, overview of commenting platforms and other web 2.0 resources which were born for and within the astrophysical research community, from 2004 to 2016. Additional experiences, chiefly in the physics domain, were added for a total of twenty-one tools, inclusive of four items in the specific area of epijournals – plus four supplementary resources which have been simply mentioned or anyway much more synthetically described due to their specific features –, thus casting some light onto an unexpected richness and consonance of endeavours. These experiences rest on the contents of the pioneering database ArXiv, which adds to its universally recognized merits that of setting the grounds for web 2.0 resources, and research behaviours, to be put in place.ELETTRONICOenConference paper10.3233/978-1-61499-769-6-100http://ebooks.iospress.nl/publication/46646ERC sectors::Social Sciences and Humanities::SH2 Institutions, Values, Beliefs and Behaviour: Sociology, social anthropology, political science, law, communication, social studies of science and technology::SH2_11 Social studies of science and technology
