Errata

If and when any errors are found in this book they will be published here along with their corrections.

Batches of errors will be corrected in the version of the book available for print-on-demand, so they will be collated in separate sections below. 

Unless your book was printed before the first batch of corrections, the date to which errata corrections have been included will be given with the copyright on the page facing page (i). 

For copies printed before 1st February 2026
