The first scholar to give information concerning the St Adalbert Codex was T. Trzciński, in his published catalogue of the manuscripts in the Chapter Library of Gniezno. On the basis of the details noted by Trzciński and probably on the basis of his own review of the manuscripts as well, W. Semkowicz published several palaeographical notes on the St Adalbert Codex (= AC) along with a photograph of p. 267 of the document. Apart from these summary notices, the codex in question has not been further studied.
