The desLibris e-Reader

The new desLibris e-Reader app is available for free download by any authenticated user of desLibris,

  • Now available for IOS and Android devices; Microsoft coming in 2017.
  • Renders both ePUB and PDF. 
  • Provides browsing, sorting, searching and download options.

The desLibris e-Reader is designed to work easily with any authenticated book or public document in desLibris. But its application is broader as a result of the OPDS and DRM standards adopted by desLibris.

What is OPDS and what does it do for a library and its users?
OPDS is an open standard used by content aggregators for providing ebook metadata and content. “Content aggregators” may be commercial, like CEL and Feedbooks, or not-for profit, like Open Library. And increasingly OPDS is being used by libraries as a standard for data exchange. Library Simplified, an international library initiative to improve library management of ebooks, has adopted OPDS as its standard, so libraries throughout the world will be moving to the standard. 

What about DRM?
The desLibris e-reader is built on the Sony/DADC User Rights Management System, which is a lightweight but powerful system for protecting copyright while at the same time simplifying the user experience. The desLibris patron account (based on an email address) is the only ID required. So once a user is known to desLibris, authentication is simple and secure.

Once a user is “known” to the Sony system, any content protected by URMS (whether purchased or borrowed from a library) is accessible under the terms of the original purchase or loan. 

The Library Simplified initiative has, for example, adopted URMS as its standard DRM. As library systems begin to implement the standard, more content will become available.

What about Open Access and Public Domain Content?
The desLibris e-Reader allows you to download, store in your bookshelf and read any public document in PDF from desLibris or your local computer.


The desLibris e-reader is built on the Sony DADC User Rights Management Solution, which is designed to support a wide variety of educational and library use cases, while giving content owners the most powerful eBook security on the market.

URMS features the same anti-tamper technology used to effectively protect video games such as Call of Duty and FIFA15, the kinds of products most targeted by hackers.

Simple User Experience

URMS is an API-based system, which allows licensors to grant access without a separate ID, like an Adobe ID. The desLibris user account (based on an email address) is the only ID required. So once a user is known to desLibris, authentication is simple and secure.

Business Models

URMS supports a variety of creative business models, including

  • multi-user, time-delimited classroom licenses. Publishers sell (or, in effect, rent) content with a single license, allowing a specified number of users to download and read for a specified period of time. The license may be renewed without requiring users to re-download.
  • single-user licenses for examination copies which may be upgraded simply to time-delimited (or permanent) desk copy licenses.
  • a license may be converted from one license model to another during the term of the license.
  • individual chapters within a file may be set to “sharable” to allow licensed users to share entire books with another user; leaving only the sharable chapter readable by the unlicensed user

This flexibility allows for these scenarios:

  • A four-month license for 35 students.
  • A purchased eBook with a conventional single-user license but where the first chapter is unlocked, allowing a user to share the book with friends who can read the first chapter.
  • An eBook distributed for free to employees with a revocable license, allowing a particular user’s access to be terminated, or allowing an obsolete edition to be expunged across all distributed copies.
  • A purchased eBook lent by its purchaser to a friend; the purchaser can no longer read, but the friend can. The friend can return it, or the original purchaser can retrieve it - a nice instance of an eBook allowing users to do more with the eBook than they can with the print book. The content owner can permit one or more lends by the purchaser, or none.
  • A group of titles with a conventional single-user library lending license could be changed for a period of time to unlimited simultaneous lends around a particular holiday promotion or backlist promotion ahead of an author’s newest book.
