There is some difference of opinion as to the exact number of copies circulated, all founded on the facts given in the _Spectator_ itself. In No. 10, Addison says that there were already 3000 copies distributed every day. "So that if I allow Twenty Readers to every Paper, which I look upon as a modeſt Computation, I may reckon about Threeſcore thouſand Diſciples in London and Weſtminster". On July 23, 1711, he wrote: "... my Bookſeller tells me, the Demand for theſe my Papers increaſes daily," and on December 31 he repeated, "I find that the Demand for my Papers has encreaſed every Month ſince their firſt appearance in the World." On the 1st of August, 1712, St. John's Stamp Act came into force, by which a halfpenny stamp was imposed upon all newspapers and periodical sheets. This attempt to suppress free expression of opinion succeeded to some extent; many of the papers of the day ceased to exist. The _Spectator_ continued as before, but the price was raised from one penny to twopence. "... A payment of over £20. a week for stamp duty represents a daily circulation of more than 1,600 copies, or 10,000 a week, from the 1st August to the 6th December 1712, and the daily circulation before the 1st August would therefore be, according to Steele's statement, nearly 4000." Two hundred and seventy-four of the 635 papers are attributed to Addison, and from 236 to 240 to Steele. Addison usually signed his essays with one of the letters of the name Clio, and Steele wrote over the initials T. and R. Besides the two principal writers, Budgell, Hughes, Parnell, Pope and Tickell are thought to have contributed papers, but considerable uncertainty exists with regard to their work. Folio.
