Ingenta Connect and Ingenta Open Publishers can now augment the PDF content delivered via Ingenta with individual and group annotations. These new features give publishers more customization and control in providing researchers and students with an easy way to make private notes or enter into collaborative discussions with peers.

In February 2017, the W3C standards body for the web approved annotation as a web standard, kicking off the era of interoperable, standards-based annotation. Annotators on Ingenta-hosted content will no longer need to worry that their notes and conversations will be locked into a proprietary tool beyond their control and potentially inaccessible to them. When operating in accordance with the standard, annotation clients should work like email clients today — users operating on different services will be able to create annotations that interact with those of others regardless of which service they use.

Who is annotating? Researchers are using annotation to organize their own private notes, collaborate with their peers, and update their publications, connecting them with resources and data across the web. Teachers are using the service — standing alone or through a Learning Management System integration — to assign close readings and collaboration projects for their students. Journalists are using annotation to fact-check online publications and/or to research stories. Publishers are creating a variety of group options: open “general discussion” groups that anyone can join, restricted layers for authors to annotate their own works or for exposing peer review summaries, layers that provide information around metadata entities, such as Research Resource Identifiers (RRIDs) or other standard identifiers. Annotation is also being used in the peer review process, enabling reviewers to add their remarks on top of draft articles and allowing editors and authors to respond accordingly. Publishers are also discovering additional uses for annotation all the time, including the creation of production groups to annotate on top of xml staging sites, editorial teams marking up websites to indicate upcoming changes, and marketing departments tweeting out annotations as promotional material or connecting media mentions back to published articles.

“Custom annotation layers give publishers new ways to engage people directly in the version of record,” said Heather Staines, Director of Partnerships at “Now branded, moderated conversation and additional resources can live right alongside publications, making them more useful and richer for everyone.”

In 2015, the Annotating All Knowledge Coalition was formed to bring together annotation enthusiasts, including Ingenta, for collaboration around interoperable experiments. Today, that group numbers more than 70 members, including universities, publishers, platforms, and technology companies. Membership is free. Information is available online:

Ingenta publishers wishing to create their own branded and moderated layers can work with to enable this new functionality. Supported integrations include multiple publisher groups with the requisite permissions levels, customized configuration of the annotation client to fit with publisher websites, full customer support, and programs for adoption and success.
