ABSTRACT
In April 1681 Roger L’Estrange closed an edition of the Observator – his half-sheet, serial, dialogue publication which ran between April 1681 and March 1687 – with this advertisement:
Whereas several Papers of Advice have been sent to the Observator from Persons to him unknown, which he dares not to Trust to, for fear of being Impos’d upon; This is to desire, that all such Notices, for the future, may be so Certify’d, as that the Matter of Fact may be Ascertain’d, Directing then to M. Brome the Publisher of This Paper.2
