collection of ebooksThings are really on the upswing for those who like their eBooks. We have a host of digital eBook readers jostling for space. There’s the iPad with its shoulder to the door and we have always had quite a few software readers since the early days. I still love the the press smell of a new book and the charm of turning a page. But I also believe that eBooks have two things going for them – convenience and availability. If you are missing the ‘charm’ bit, here’s KooBits for you.

KooBits is a collection manager for all the eBooks you have scattered on your computer. Think of it as a centralized library for organizing and managing your eBooks. That it’s a free download isn’t the only charming bit about it. Apart from being an eBook manager, KooBits is a lot more.


KooBits is available for both Windows and Mac. It’s a mere 12.3MB download. The only other requirement for this freeware is that you have Adobe Air installed. One of the benefits of Adobe AIR is immediately apparent in KooBits rich glossy look.

The slick interface is the first appealing tug that will make you feel like putting up all your eBooks on its shelves.

Organizing Your eBook Shelf

KooBits can open popular eBook formats like PDF, EPUB, XML, HTML, KBJ, and more (that includes animation).

Importing all your eBooks and creating your shelf is a browse and add operation. If you have them all in one folder, it makes your task that much easier. The cover thumbnails are large enough for you to glance through your collection without squinting at the titles. You can rearrange the order of the books with a drag “˜n drop.

The library has three default categories. If your reading interests are spread across the board, you can create your own categories. In fact it’s an organizational tip because KooBits does not have a feature to add tags or any other form of filter. The new categories fall below the three default categories. You can even give them a choice of icons.

KooBits lacks the feature to add more to each book’s description. Clicking on the title and then View info doesn’t give you any scope to add your own information.

KooBits has a list view (List Mode) which is more mundane when compared with the neatness of the Shelf Mode.

Populate Your Book Shelf With Free eBook Downloads

Even if you don’t have a great collection of eBooks, and the shelves are lying vacant, KooBits gives you a couple of options to fill them up.

The Bookstore is where you can head to for downloading paid and free titles. Get the free account registration done first. If you don’t want to shell out the dollars, check out the free titles that are available across the genres. With a single click you can download a free book to your library. Free books are in the public domain and you can find a lot of titles on online book resources like Project Gutenberg.

The Drop Box is like a daily mail service which “˜drops’ a random free book (according to the genres you specify during the account sign-up) into your KooBits account. Each eBook delivered to your Drop Box is only available for free on that day.

What KooBits lacks is a search tool for wading through all available titles.

Reading eBooks On The Viewer

collection of ebooks

You don’t have to use an external program to read the collection of eBook titles you have been saving up. The Viewer is the tool for the job. There’s plenty to like about it: a multi-colored Highlighter, a Stamp tool for symbolic annotations on eBooks, and a Crop Image button for extracting content from any eBook and saving it on the Scrapbook. All extracted content is stored in the Scrapbook on the sidebar.

You can set up the reading screen with a few options like Scrolling, Flipping, and Sliding.

Should You Put All Your eBooks On KooBits?

Why not? Even though KooBits still has some bits missing, the sum of its parts is still appealing. There’s no search feature yet. Filters to handle a large collection aren’t in place. An automatic pinging of Amazon to access a book’s information would have been really handy. The viewer does not have a zoom. But then you might not miss these features right now as the basic functions serve adequately and slickly.

Download KooBits 4.0 and let us know if the eBook collection manager holds an appeal for you.

    I tried Koobits on both fast desktop and slow netbook.
    While loading 100+ books took about 10 minutes in a netbook, the program was snappy and usable.
    My main grips:
    1. The list view is useless - you cannot open a book from the list view, neither to jump to the selected book in the thumbnail view.
    2. While I was importing books to a custom shelf, all of them ended up in a "Local books shelf".
    3. There is no way moving multiple books from shelf to shelf.
    4. My main gripe (a deal-breaker) is that Koobits "forgets" the last opened book every time it is closed (not minimized, but exited). To navigate to that book is a pain in a thumbnail view with a hundred+ books and list view is navigationally non-functional.

    Don't know why my first comment did not show up. I just want to suggest a excellent alternative for ebook reader called NOOKstudy by Barnes&Noble. After trying out both KooBits & NOOKstudy. I found NOOKstudy to be prettier, highlight & note taking is more polished. I does support epub & pdf. Eventhough it was designed for students using etextbook, it is free to download to use with your ebook collection. Just pick any school affiliation when asked. One limitation that I found is you have to register account with barnes&noble and adobe (they are free though).

    Thank you very much. I was searching for a software just like that. Blio does not open pdf. Calibre converts the files first. Going to test it now

    Hey KooBits.... My son installed the software for me on my computer and he picked the topics of interest. I notice that I cannot adjust the topics ot add or delete. Is there something I am missing?

    I would love to use this, but for whatever reason (my laptop isnt that old, 2007, with win vista) its deathly slow with adding my PDF files.
    1 to 4 files is ok, but if I add more than that for adding to the local library, it runs and runs and runs, and does nothing for hours...

      That's odd. My laptop is the same vintage though with WinXP and I tested it out with a folder of eBooks (about 12 of them).

    Aside from the "pretty" and the scrapbook it seems to have nothing at all to offer to tempt a Calibre user away from that tool. No organization, no tags, no custom info, no conversions.

    • Saikat Basu
      January 9, 2011 at 6:23 pm

      No, it's a simple tool as I mentioned in the title. Calibre is THE comprehensive reader.

    i will stick to calibre for now, but i have to say this looks very good

    • Saikat Basu
      January 8, 2011 at 10:47 am

      Yes, in the looks department it competes quite well with Blio. But unortunately, Blio only opens EPUB formats while this one covers - PDF, EPUB, XML, HTML, KBJ.

    I couldn't find a Mac version on their website or elsewhere.

    • Saikat Basu
      January 8, 2011 at 4:12 am

      Neither did I. But all web mentions point to it. As it runs on Adobe Air, I wondered if the download page recognizes the O.S version automatically. As I don't use Mac myself, I couldn't really test it out.

        Yeah I'm not seeing any Mac version either.

        The download is an .exe file, so no joy for Mac users.

          January 29, 2011 at 9:39 am

          The developers say that the Mac version is going to be launched in Feb.
