Currently, Adobe Content Server 4 is pretty much the industry standard for eBook DRM systems. It can protect the most popular eBook formats, ePub and PDF, and perhaps its greatest strength is that it does so without locking end-users into a single device, platform or vendor. It is probably why many industry giants like Google Editions, Barnes & Noble and Simon & Schuster have adopted Adobe Content Server 4 instead of developing their own eBook DRM system.
So what does this mean? Technically, it means that anyone can setup their own eBook DRM system and sell eBooks through their own website. All the while, their system would be compatible with hundreds of reader devices and mobile apps, as well as PCs and Macs with the free Adobe Digital Editions Software. (You can see a complete listing of supported devices and apps here.) And most large publishers allow you to reseller their eBooks if you have Adobe Content Server 4 deployed as your DRM solution. Therefore, you could build a large catalogue of popular eBooks to sell rather quickly. This all sounds great and all, but there has to be a catch, right? It turns out, there is.
Adobe Content Server 4 is a great eBook DRM system. However, it is both prohibitively expensive and technically complicated for small to medium size self-publishers and eBook resellers. Its pricing as of today is as follows:
- $10.000 for the software license (one-time)
- $1.500 / year maintenance
- $0.22 for each eBook activation (first time an eBook is accessed by an end-user, also called fulfillment)
