Books and Publications - the final product of the translation is to be published and thus reach a wider reading audience (books, newspaper or periodical articles, academic dissertations, etc.) or distributed in electronic form (CD/DVD). The published translation receives an ISBN number or other kind of identification number. Before reaching the printing house, the text is proofread by a native speaker and verified by an expert in the given discipline. This double - linguistic and content-related - verification guarantees that the published text is free of substantial errors and conforms to the formal conventions of the target language.
