Theory of classification and classification in libraries and archives: convergences and divergences

The classification structures and systems are privileged resources for knowledge organization. Given 29 this statement, the paper presented here refers to a study developed in the information representation and organi30 zation field, dedicated to the theory of classification, in general, and to the classification in libraries and archives, in 31 particular. In this endeavor, we adopted an exploratory approach, performing a selective literature review of the 32 subject, presenting and discussing theoretical and empirical considerations focused on backgrounds, influences, 33 definitions, purposes, relevance, principles and characteristics of bibliographic and archives classifications, in order 34 to identify points of convergence and/or divergence between them, thus contributing to a better understanding 35 and application in a contemporary sense. Following this theoretical framework, we performed a comparative 36 analysis of the relevant aspects of the mentioned classifications, having reached the following considerations: the 37 two types of knowledge classifications considered have some points of convergence; in general aspects, regarding 38 their backgrounds, influences, definitions, purposes and relevance; however, in what regards specific aspects, such 39 as the principles that govern them and their characteristics, they show differences which, in our opinion, are 40 caused mainly by the specific characteristics of their objects, as well as by the constraints of their own context
