    Notes:

    Numbers in the parentheses of the born/died information denotes the translators' born/died year.
    Some of the born/died information of the authors and the translators of the wource data, catalog.rdf provided by the Project Gutenberg, have interrogation marks, which were stripped off in the table of this website for ease of processing the data.
    The authors and the translators displayed in the table are only one of multiple data stated in the catalog.rdf, if the work is composed by more than one author or translator, for ease of processing the data in this website.
    The "Pages" shown in the parentheses at the "Word Count" are the results of the division of the "Word Count" by 400, where this website assumes a page of a book includes 400 words.
