In July 2009, the American Psychological Association (APA) published a new Sixth edition of their Publication Manual of the American Psychological Association.
Several errors have been discovered in the 1st printing of the Sixth edition and APA is providing a PDF noting the corrections at:
//supp.apa.org/style/pubman-reprint-corrections-for-2e.pdf
A link to the corrections also appears in the Quest catalogue record for the Publication Manual of the American Psychological Association.
Our libraries will be replacing 1st printing copies of the APA Style Guide with corrected 2nd printings post haste.
