Tools

This week, Barnes and Noble College, a subsidiary of Nook Media, announced it had made significant updates to the open source EPUBCheck tool, which provides a way to ensure eBooks published in the ePUB format adhere to the defined standard.

Once you create an eBook in the ePUB format, you can run it against this tool and determine if there are any errors in the file that make it not adhere to the defined standard. The updates, which were developed by the Nook Digital Education team, hope to make it easier to manage and simpler to include the tool as part of the overall eBook creation workflow process.

The tool was originally developed by the International Digital Publishing Forum and Barnes and Noble's team has taken that original piece and built this new functionality on top of it.

According to a statement from Barnes and Noble, updates "include tests for content accessibility markup, CSS issues that might affect presentation quality, and tests for specific script usage patterns that require security consideration that will help publishers create exceptional, accessible, EPUB 3 content." 

Arwen Pond, Software Engineer at NOOK Media, says the team added this new functionality making the tool more powerful for everyone who uses this format, "The new features we added will help publishers create exceptional EPUB 3 content, while successfully implementing this new industry standard," Pond explained in a statement. 

Barnes and Noble supports the ePUB standards, so it's in their best interest to develop or enhance tools to help advance the standard. This tool should prove useful for organizations building ePUB ebooks to help them find mistakes that could make it hard to read for some viewers, and make the check part of a defined workflow.

The updated tool is available for free to all at idpf.org.
