Shurpu answers a different question from Maqlu, and the two together show a system of diagnosis at work. Maqlu asks who did this to me. Shurpu asks what have I done. The sufferer in Shurpu is bound by a mamitu, a curse or oath-sanction that has come into force because some obligation was broken, and the crucial feature is that he may not know which one. He is not being attacked. He has stepped on something.
The remedy is therefore comprehensive rather than targeted. The series recites the possible offences at length, so that whichever applies is named and released, and it is that list which has given Shurpu a readership far outside Assyriology. It runs from the plainly religious, contempt for a god, a broken oath, to the plainly social: moving a boundary marker, refusing a beggar, setting a son against a father, dividing a family, saying one thing with the mouth and another in the heart. It is not a law code and it is not a moral treatise. It is a list of the things a Babylonian expected might be silently held against him.
Erica Reiner's 1958 edition remains the standard, and her arrangement of the material is the one the literature cites. Her edition is in copyright, and this atlas describes the contents of the list rather than reproducing her translation of it.
