In contrast to Johannes Bugenhagen, who in 1518 based his Latin "Pomerania" on a limited amount of sources from abbeys and printed sources, Kantzow also had access to the extensive ducal archives, where he gathered most of the information for his chronicles, and further derived historiographic information from archeological remnants, inscriptions, coins, folklore, eyewitness accounts and own experiences. The table below provides an overview of the major chronicles written by Kantzow:  The first chronicle written by Kantzow was "Fragmenta der pamerischen geschichte", full title: "Fragmenta der pamerischen geschichte, vth welcker (so man de tide recht ordent, vnd dat jennige wat vnrecht ist recht maket) men wol einen guden wech tho einer Croniken hebben konde" (English translation: "Fragments of the Pomeranian History, from which (if one orders the time properly, and makes right what is not right) one may well gain a good access to a chronicle"). Wilhelm Böhmer, teacher in Stettin and member of the Society for Pomeranian History and Antiquity Studies, rediscovered the handwritten chronicle in landlord von Löper's library in Stramehl (now Strzmiele) in 1832. In 1835, Böhmer published the transliterated script in a printed book titled "Thomas Kantzows Chronik von Pommern in niederdeutscher Mundart sammt einer Auswahl aus den übrigen ungedruckten Schriften desselben" (English translation: "Thomas Kantzow's chronicle of Pomerania in Low German tongue including a selection of further unprinted scripts of the same [author]"), which did not alter Kantzow's spelling. In the preface, Böhmer postulates that the chronicle was written after 1531 or 1532, and a few years before 1538, a determination also followed by Berger (2001). In ADB and NDB, a date prior to 1538 is assumed. Kantzow's friend Nicolaus (also Niklaus) Klempzen (also Klemptzen) had added a note to the original manuscript's title reading "by Thomas Kantzow anno 1538", also a second front page was attached to Kantzow's original one, which Böhmer assumed to originate from the ducal chancellory, which read "First volume of fragments, from which deceased Thomas Kantzow has written the Chronicon Pomeraniae", written in Fraktur letters, with "1538" added in another handwriting.
