EPUB: NEW OPEN STANDARD IN E-PUBLISHING STUDENT NAME: Blazej Blazejewski STUDENT NUMBER: 04-215-125 COURSE NAME: E-Business DEPARTMENT: DIUF SUPERVISORS: Andreas Meier / Luis Terán DATE OF SUBMISSION: 17 05 2011 ABSTRACT The aim of this paper is to analyze the EPUB file format used to produce and distribute e-books. The paper is divided in two parts. The first part is devoted to the technical aspects of EPUB files. After a brief historical introduction, the current 2.0.1 EPUB specification is thoroughly discussed and a fictional and simplified EPUB file is described in detail to provide a practical example. The future 3.0 EPUB specification is briefly presented afterwards, and the first part is closed by a critical evaluation of the EPUB file format. The second part puts the EPUB file format into a broader economic perspective of the e-publishing value chain. For this reason, the second part starts with the description of e-publishing and the e-publishing value chain. This introduction is followed by a presentation of advantages of EPUB files over traditional printed books with a special focus on production, distribution and pricing. Finally, the second part of the paper compares the EPUB file format with other popular file formats used in e-publishing. Keywords: EPUB, PDF, e-books, publishing, e-publishing 2 CONTENTS ABSTRACT
