Frequently Asked Questions

Bandcamp for books, comics and magazines.

  1. What is Bubblin Superbooks?

    Bubblin is a social book reader for web—an online café of books. Meaning, a calm and cozy place for book lovers to hang out and read Superbooks . Share and discuss books with friends and family.

    Bubblin is free of charge, free of ads and doesn't require registration to be able to enjoy or share books.

    We guarantee a distraction free environment!

  2. Are all the books free?

    All public domain works processed by our team and few of the books created by other makers on Bubblin are free to read and share with anyone. We have recently started allowing premium books on Bubblin but this feature is available only through invitation at the moment.

    ☞ Please see question #18 below if you're interested in having your book published for a premium.
  3. How do I download a book?

    Explicit downloading by clicking a button is not required.

    Once you open a book on your browser, it will install itself locally and continue to work offline without an Internet connection. This process of offlining is frictionless and carried out seamlessly using a service worker under the hood.

  4. But, I like reading offline…

    Yes, and we support offline reading!

    All books on Bubblin are offline-first by default. Your book(s) will work if for some reason the device you are on loses connection to the Internet.

  5. Can I turn off page curls?

    Yes, page curling can be tuned for speed and turned off.

    Head over to Bubblin > Settings > Account > Page turns to make adjustments or to simply turn it off.

  6. Do I need to purchase hardware?

    No. One of the important goals of Bubblin is to liberate digital books from properietary hardware. No investment in hardware or specialized software is required for you to be able to read or share books on Bubblin.

    Our books are generally supported on all modern browsers, all devices and all operating systems.

  7. Is this another e-book format?

    Superbook is a native book format for the web. Unlike ePub or any other 'file format' that lives outside of web, a Superbook is a website. By definition, Superbook means superclass of an object like book. You might want to head this way if you're interested in how Superbooks work and what are they made of.

  8. How is the support?

    A blank Superbook is supported everywhere.

  9. How is the support on e-readers?

    Not quite there yet.

    We tested on a few e-readers on market that sport a web browser but the results weren't satisfactory. One approach to solving this is to have Superbooks default to plain HTML with typical styling that scrolls when JavaScript is turned off. More updates on e-reader support, especially w.r.t WCAG 2.1 (2018) accessibility guidelines will be announced shortly.

    We discuss some of these issues, native behavior and accessibility consideration at length on the Frequently Raised Concerns page. Welcome to join the conversation and help us build a better system!

  10. No really, what is a Superbook?

    Superbook means Superclass of a book, comics or magazine.

    Put simply, it is a jacket that holds a story together. More explanation about how it works is provided in documentation. The key difference between a Superbook and a traditional e-book is that Superbooks use a strong layout as opposed to fixed or fluid one elsewhere.

    Each page on a Superbook is a virgin iframe—a sandboxed code playground—that accepts a very limited quantity of content that always remains above-the-fold. Since the content of an iframe is ultimately good old HTML, CSS and JavaScript i.e. building blocks of web, you can safely utlize frontend engineering skills to longform storytelling to create classiest of books ever!

  11. Does it mean we can add code inside of books?

    Yes, absolutely! As a storyteller you can add programming logic into your book to make it more compelling. That's the magical part of it… 🙂

    Output visual experiments on your book or provide an interactive explanation of some sort. Add contextual substance like a dynamic illustration as shown below that helps the reader understand or grasp key concepts easily.

    You can use keyboard shortcuts to navigate on the book:

    arrow keys or the Space bar to turn the page. Press ⌘ + K to see more options.

    The content could be anything from plain text to GPU powered shaders. Given that a Superbook can render plain text trivially, all novels, textbooks, magazines and comic books that exist as files outside of web can now easily be ported online.

    Here are some of the advantages of Superbooks over the traditional files. You might want to stop pushing your readers to download before they can read. Just give them the book right away!

  12. Please list the main USPs:

    Sure. To begin with, Superbooks work everywhere: on every device, mobile, tablet, desktop and television on the planet. This makes it easy to for you (the writer) to reach your readers anywhere.

    Since we don't use a file system for distribution and rely on web instead, our books are way more accessible and shareable than on any other platform or option on market.

    Superbooks allow coding inside of book letting you create contextually relevant experiences over static rendered content. Such flexibility isn't possible on a lifeless file that lives outside of web.

    For example:

    1. Add a little canvas experiment in your physics book to explain pendulum motion.
    2. Code up a comics book with animated CSS3 characters instead of using heavy GIFs.
    3. Publish a photobook capturing all your memories at one place.
    4. Create a children's book with music and story that goes hand-in-hand.

    and so on…

    We believe that adapting books on web can lead us to a stronger and better web. A web where people can enjoy reading longform straight off their browsers. Without needing to download an artifact to the disk and without needing to own specialized and often closed hardware for books. It would also lead us to better books with endless creativity, likes of which we haven't seen before. To sum it up, web and books together means better access, better storytelling and thus a better world.

  13. Can I upload a file to publish it like a book?

    Not yet. We are working on this!

  14. Can I publish on Bubblin?

    Absolutely! Feel free to start on our documentation page, but here's a quick summary of the process:

    There are two methods to write and publish a Superbook:

    1. Use the in-browser editor on Bubblin, or
    2. Install Bookiza Abelone, an open source book reification framework for web.

    The first option (in-browser editor) is suitable for small one-off publications like comics or magazine. The second option i.e. Bookiza is a more professional setup meant for long hauls or something periodical. Bookiza comes with several pre-built templates for books of different genres and literature like textbooks, photobooks, novella etc.

  15. I use Scrivener, does it work for me?

    We're looking at integrating deeply with Scrivener using intermediary format called Markdown.

    An update will be made available when the integration is completed.

  16. Does it work with MS Word too?

    It is possible but not recommended at all!

    Microsoft Office (Word) is an enterprise software meant for creating business documents like contracts or LOIs. Therefore, the quality of HTML that comes off of it for adoption on web is very poor. A lot has been written about this in past, but to repeat: if you're considering writing and publishing your book on web, we recommend you to avoid using MS Word completely.

  17. Is there a tutorial?

    Here's a quick one using the in-browser editor and layout templates.

  18. Can I sell my books?

    Yes, but only licensed work is allowed!

    For example, you can publish and sell all original and unencumbered works written by you. Or republish and sell public domain books with or without your own take on it: such as with new artwork, illustrations etc. In general, to be able to sell, you must be in possession of the right to do so for the material in question. Any content on Bubblin must not be prohibited per our forbidden list described on Terms of Service.

    Starting a new book or want to publish an existing one? Get in touch with us immediately.

    ☞ Please note that the pricing tool is available only through invitation.
  19. Is this self-publishing?

    Well, not exactly. It's more like book making that inspires from the latest app development techniques such as frontend development, push2deploy etc.

    Book writing isn't an individual activity. You will need help from your friends, editors, illustration artists, layout designers, domain experts and other specialists to polish your work (enter Git for collaboration) before it is ready for the world.

    You might want to look at Bookiza — an open source book reification framework for the web.

  20. Is there an iOS or Android app?

    Native apps are planned. Our first love is web; also it is the last.
