The original spelling of the book has been retained, even when wrong (Bosone da Gobbio [Gubbio], Bezalu, near Perpignon [BesalÚ, near Perpignan]), or variant (Juda/Jehuda/Jehudah Halevi/Halevy). The original transliteration of Hebrew words, which does not always follow uniform rules, has been preserved. Similarly, inaccurate quotations (e.g. Falstaff's remark “I told you John a Gaunt...”) were not rectified.
