Early modern books were not stable or settled outputs of the press but dynamic shape changers, subject to reworking, re-presentation, revision, and reinterpretation. Their history is that of multiple agencies as their texts were transformed in ways that their original authors might hardly recognize. Processes of editing, revision, redaction, selection, abridgement, glossing, disputation, translation, and posthumous publication resulted in a textual elasticity and mobility that could dissolve distinctions between text and paratexts, textuality and intertextuality, manuscript and print, author and reader or editor. Taking the period between the lapse of the Licensing Act and the dawn of industrial press production, this introduction, focusing on Richard Baxter and Samuel Taylor Coleridge as the ’bookends’ of the collection, reviews the varieties of transformation to which printed texts were subject, and the kinds of transformation they sought to effect, with reference to each of the ensuing essays.
