All known errors in the first printing (October 2014) are corrected in the PDF here. The second printing from July 2015 corrected all the errors in the first printing. (It is a bit difficult to tell the first and later printing apart. If the acknowledgements page xv has ‘Shomu Banerjee, Atlanta, USA’ at the bottom, then you have the second or later printing.) A third printing (without changes) is scheduled for December 2015.
Individuals may submit errors via email to email@example.com.
I thank Joon Young Ahn, Robert Avery, Stephen Cheung, Geunyoung Kim, Kate Mitchell, Ariana Rahgozar, Jean-Christophe Spiliotis-Saquet, and especially Pin-wen Lin for bringing errors in the first printing to my attention.
