Dear all at AoIR, this email is for those of you who are interested in early internet history. Please be informed that a new book has been published “On some Pioneering Usenet Newsgroups in Astrophysics”. I am the author. It is true that the subject is disciplinary, but some major steps in the evolution of Usenet newsgroups at large have been conveyed. Also, an insight into the perception and use of these early cmc tools by the research community concerned has been tentatively given. The book is open access. At the moment it can be found on the publisher’s website at https://mucchieditore.it/prodotto/on-some-pioneering-usenet-newsgroups-in-as... but it will be made available also - e.g. - on my ResearchGate account in the next future. Any comment is welcome; you can contact me at the email address monica.marra@inaf.it Regards, Monica Marra -- Dr. Monica Marra, technologist INAF - OAS Bologna via Gobetti 93/3 40129 Bologna, Italy https://www.researchgate.net/profile/Monica_Marra Teleworker Working days: Monday, Tuesday, Wednesday
