This article presents the most relevant information on the history of dialectological research in Poznań and its context, the academic achievements of the Poznań University enjoyed in cooperation with the Poznań Society for the Advancement of Arts and Sciences. The two institutions have greatly contributed to the development of Polish studies including dialectology. The presented information pertains chiefly to the relatively unknown accomplishments of the dialectology team, for example a phonographic archive containing recordings of utterances of informants born in the second half of the 19th century (the oldest interlocutor was born in 1855). Together with contemporary recordings, the collection contains approximately 3,700 hours of rural speech. The entire archive is available in a digital version. The text is supplemented with information about the history of Poznań dialectology and the contemporary activities of the team of the Dialectology Workshop at the Poznań University, mainly lexicographic works.
