Added to the Molinari Institute’s online library: two 19th-century British individualist anarchist texts – Henry Seymour’s Anarchy: Theory and Practice (1888) and Albert Tarn’s The State: Its Origin, Its Nature, and Its Abolition (1895). Thanks to Jonathan Martindale for locating and transcribing these texts!
Both Seymour and Tarn occasionally appeared in the pages of Benjamin Tucker’s Liberty. Curiously, there’s currently an institute named after Tarn; but its website doesn’t have much information.
