William Shakespeare 
The Tragedie of Othello, the Moor of Venice [PDF ebook] 

The ‘Shakespearean Originals’ series aims to provide readers of modern drama with 16th- and 17th-century playtexts which have been treated as historical documents, and are reproduced as closely to their original printed forms as the conditions of modern publication will permit. Each volume in the series comprises a general series introduction, an introduction to the play, the original text, a select bibliography, full annotations and some sample facsimile pages from the text itself.
