We offer methods for the formation of digital collections from a set of documents (scientific articles, monographs, collections of reports), which are presented in various storage formats. Based on the analysis of the structure of documents and the stylistic features of their design, we have developed an algorithm for extracting the metadata of these documents. We present a software tool for dividing collections of articles into separate documents and the formation of their semantic presentation. On the example of a collection “Proceedings of the Mathematical Center. N.I. Lobachevskii”, which have a different format and structure, we describe the algorithm for creating a digital collection and its inclusion in the Lobachevskii-DML.
