I recently had to create a digital book for one of my clients.  Little did I know it was not possible to create one that flips pages online with my Adobe Creative Suite. After a bit of research, I found a couple of companies that do just that.  I ended up using InstantFlipbook.com because they offer a paid and done service, with no monthly subscription fees.  Basically, if you have a pdf version of a booklet or your book, you can upload it to this service and it converts instantly to a flipbook that you can turn the pages online.  Click on the photo to see how it works.

The service then lets you download a copy to use on your website.  I think it is a great idea for marketing a book if you are an author, or distributing an online magazine. It works well on tablets and smartphones.  

The other comparable company I found is Issu.com.   They offer a subscription-based service with tiered pricing.  You can then sell the subscription or sell one issue on their website. You can do the same thing with Instantflipbook.com but you would have to sell a subscription on your own website or social media accounts. 

I think it is a great service for authors and online publishers.  I can help put it together for you too, just email me for more information.
