Nomenclature
Every runic inscription is shown with its ID code that is used in scholarly literature to refer to the inscription, and it is only obligatory to give the first two parts of it. The first part is one or two letters that represent the area where the runic inscription appears, e.g. U for the Uppland, Sö for Södermanland and DR for Denmark. The second part represents the order in which the inscription is presented in the official national publications (e.g. Sveriges runinskrifter). Thus U 73 means that the runestone was the 73rd runic inscription in Uppland that was documented in Sveriges runinskrifter. If the inscription was documented later than the official publication, it is listed according to the publication where it was first described, e.g. Sö Fv1954;20, where Sö represents Södermanland, Fv stands for the annual publication Fornvännen, 1954 is the year of the issue of Fornvännen and 20 is the page in the publication.
