    Since 1 January 2007, ISBNs have contained 13 digits, a format that is compatible with "Bookland" EAN-13s: ISBN-13 (P212). --Kolja21 (talk) 17:06, 15 October 2013 (UTC)[reply]

    I am going to respond on Property_talk:P212 because I believe that the two properties should be merged. Maximilianklein (talk) 19:06, 17 October 2013 (UTC)[reply]

    Changing English description[edit]

    There is no official correct presentation, all hyphenation is completely optional. Maximilianklein (talk) 22:33, 25 October 2013 (UTC)[reply]

    Till you changed the description it wasn't optional ; ) The hyphens are needed for human readers without eidetic memory. en:Wikipedia:ISBN#Types: "Use hyphens if they are included, as they divide the number into meaningful parts." --Kolja21 (talk) 22:51, 25 October 2013 (UTC)[reply]
    No, the hyphens have a meaning: they separate logical groups: in ISBN-10, the 1st group identifies a registry (one of the few major international languages, or a single country, or an special registry for NGO's and international organizations), the second group identifies a publisher in that registry, the third group is a serial number for the book, the last 4th group has a single digit (or "X") for the check code. They can be used to locate the country of publication and the publisher, and in the catalog of this publisher, the year of publication (note that some countries have several blocks, and some publishers have several codes in the same country, they get new a block when their book numbers will soon be exhausted (but large publishers may jsut decide to publish in another country if it lacks some codes. ISBN-10 is convertible to ISBN-13, using the "978" prefix and by recomputing the last check digit; but the reverse is not always possible, even if the ISBN-13 starts by "978". As well, for old books published before 2005, you won't find them by their ISBN-13 in most libaries if their catalog have not converted the codes: many historic catalogs of public libraries will never be converted to ISBN-13, and cite references are often printed or ekpt only as facsimile which won't be modified (and not OCR'ed as well).
    The best practive is then to keep the format that was originally printed on the book itself. Verdy p (talk) 06:27, 25 August 2020 (UTC)[reply]

    Property should be constrained for editions but is being misused for works[edit]

    The exemplary work On the origin of species (Q20124) shows ISBN-10 (property:P957), ISBN-13 (property:P212), BiblioNet publication ID (property:P2187), and OCLC control number (property:P243) each of which should be a property of a specific edition, not of the work such editions exemplify. LeadSongDog (talk) 21:48, 13 April 2017 (UTC)[reply]

    The property can be used for instances of book (Q571) as well, especially for the first edition of a book. It makes no sense to complicate the data model by creation of two items (abstract "work" and "edition") if there is only one book edition anyway. -- JakobVoss (talk) 16:23, 27 March 2019 (UTC)[reply]
    OCLC and ISBN-13 already had "book" as an allowed class, so I added it to ISBN-10 as well. --1Veertje (talk) 09:53, 16 April 2019 (UTC)[reply]

    Proceedings constraint[edit]

    Hi, The allowable item type constraint for ISBN should include Q1143604 (proceedings) - as these are individual publications that sometimes have ISBNS (sometimes ISSNs and sometimes both). -- Phoebe (talk) 10:41, 15 August 2019 (UTC)[reply]

    I don,t see the problem. If the proceedings are published as a book, they should also have that as an instance of. Circeus (talk) 17:37, 15 August 2019 (UTC)[reply]
