A precursor to newspapers. From this British Library page:
Newsbooks were the ancestors of newspapers, printed at this time  in editions of up to 250 copies, though being read probably by a much larger number. While newsbooks became widespread during the 1640s, their origin can be traced back to official statements about public events, such as The Trewe encountre, a pamphlet published following the Battle of Flodden in 1513, and corantos, newsletters carrying collected information, which often contained reported speech.
During the Civil War (1642-51) a newspaper war broke out; the royalist Mercurius Aulicus was printed in Oxford and Bristol, even circulating in London, where it was regarded as a major problem by the parliamentarians, who eventually produced the Mercurius Britannicus to counter it.
