This book sees the publication of fifty-six letters from Tell ed-Dēr (ancient Sippar- Amnānum), almost eighty years after they were found. The group is called the Ikūn-pîša Letter Archive (IPLA), after its main protagonist, Ikūn-pîša. It was found together with a number of economic and administrative texts that Edzard edited and published in 1970. The Ikūn-pîša archive was partly studied by Al-‘Adhami in his 1967 article and 1971 thesis. The letters and other types of texts must of course be studied as one archive.
