Talking of errors, I've now detected a raft of PTS page reference errors on ATI for translations from the Anguttara Nikaya. These are the only references I've looked at in any detail, and I'm confident that mine are right, since I've been spending a lot of time with the AN helping edit Bhikkhu Bodhi's forthcoming translation.

• 1:21-40 (Thanissaro), PTS ref should be A i 5
• 1:31-40 (Woodward), the 6 suttas on this page are actually translations of 21-24, and 39-40, so the numbering should be corrected and the reference should read PTS: A i 5 (I,iii,1-4 and iv, 9-10)
