Zasoby informacyjne Biblioteki Narodowej jako źródła do badań rynku książki elektronicznej w Polsce

Abstract

INFORMATION RESOURCES OF THE NATIONAL LIBRARY AS A SOURCE FOR THE STUDY OF THE ELECTRONIC BOOK MARKET IN POLANDThe aim of the article is to present publications and databases based on legal deposit copies sent to the National Library as potential sources for the study of books on electronic media. The authors carry out a critical analysis of, above all, the statistics provided by Ruch Wydawniczy w Liczbach [Polish Publishing in Figures] 2001–2014 as well as inventories making up the national bibliography system, Bibliografia Dokumentów Elektronicznych [Bibliography of Electronic Documents] 2001–2015 and Bibliografia Dokumentów Dźwiękowych [Bibliography of Sound Documents] 2009–2011. The data obtained as a result of the analysis have been confronted with information contained in the basic component of the national bibliography system — Przewodnik Bibliograficzny [Bibliographic Guide]. The analysis has demonstrated that the statistics provided by the National Library’s publications are not useful to the study of the electronic book market owing to the fact that the data overlook the aspect of the medium. The analysis has also shown that the bibliographic information about the current production of e-books and audiobooks is incomplete. Drawing on the results of the analysis, the authors have concluded that the incompleteness of the National Library’s sources stems partly from the methodology used in their compilation and partly from problems with obtaining legal deposit copies from publishers. In addition, other National Library resources — the main catalogue, digital repository or e-ISBN service — do not, in their present form, constitute alternative sources of information about electronic books published in Poland.
