Book Mark

Found this Book Mark over on and unfortunately there’s no information on the piece. Does anyone know who we should be giving credit to? Made me look and chuckle.

  1. Here is the post about it that has all the info:

    Unfortunately I only speak English so I cannot tell you what it says :(

    Hope it helps!

  2. Hey miss,
    it´s a german one, look at this:

    A nice day to everyone

  3. You can order it online at

    I’m not sure whther they’ll deliver to the US, though.

  4. How fantastic is that!? That’s quite a clever solution. I may have to go make one now. Thanks for sharing.

  5. Oh my, the poor spine though!

  6. Man kann es natürlich auch bei Manufactum Schweiz bestellen ;-)

  7. I wonder if this is actually good for the binding.

  8. It appears Pedro is correct about the image source, it’s definitely

    In regards to Cera & Chaucee’s comments about the design adding stress to the binding, I don’t think such a design would cause any more harm than simply opening the book. It seems to me the book is given more support by this device than does the average reader.

    I contacted the Library of Congress’ Preservation Directorate for their take on this. They should reply within five business days. I will post their reply when it arrives.

  9. The LoC Preservation Directorate responded to my query. Here is what they had to say of the book mark:

    Thank you for contacting the Library of Congress Preservation Directorate.

    The bookmark shown in the link you provided is not one we would recommend using with any book of value. By suspending the book with the spine up and the fore edge down, it allows gravity to pull the textblock (the pages of the book) away from the case (the front and back covers and spine), weakening the textblock-to-case attachment. The wedge shape also forces the book into a partially open state and creates a zone of pressure in the gutter, placing constant stress on the binding. Finally, many types of wood and wood finishes are acidic and may off-gas damaging components into the book.

    We recommend using bookmarks that are thin, flexible, and made of non-damaging materials such as acid-free paper. When not in use, books should be stored fully closed and either flat or upright and fully supported on a shelf. Books should never be shelved on their fore edges with the spine facing up.

    I hope this information is helpful. Please don’t hesitate to use our Ask-a-Librarian service again should you have further questions.

    So there you go. Next time, Cera & Chaucee. Next time! ;)

  10. Wow, thanks for posting the response, Alex! The Library of Congress Preservation Directorate doesn’t mess around, does it?

  11. While cool, this could definitely hurt a heavy books binding, as others have noted.
