I’m trying to understand the DKB recommendations for including figure and table lists. Are they required for WCAG AA?
The summary reads:
Providing lists of key content, like tables, illustrations and video, allows readers to more easily return to these items later.”
But later, in the FAQs, it reads:
Should content lists be included in the EPUB navigation document?
Only if the navigation document is included in the spine.
Although these lists are an ideal for the navigation document, EPUB reading systems typically only provide access to the table of contents and sometimes the page list. This is true despite the EPUB specification requiring that there be some way to access all the content of the navigation document. Consequently, readers will not be able to access the lists when the navigation document is not in the spine.
So I’m trying to figure out: Does the book fail this criterion if the figure and table lists are present, but in a nav doc that isn’t in the spine? Is the recommendation (or requirement?) instead that the figure and table lists be visible, linked lists in the book’s TOC?
Thanks in advance!

Thank you for your question!
Lists of figures and tables are not a requirement to pass the WCAG 2.4.5 criterion but are recommended.
The criterion is as follows:
Criterion: 2.4.5 Multiple Ways
Simplified Language: Ensure that there is more than one way to locate a particular page on a site, like having menu navigation, links between pages, a search function, etc.
From WCAG: More than one way is available to locate a Web page within a set of Web pages except where the Web Page is the result of, or a step in, a process.
If page breaks and a page list are included in the EPUB, the reader can navigate to the figures via individual chapters or using the page numbers, which would fulfill the multiple ways criterion. If a separate list of figures is being included in the EPUB, it is typically added to the EPUB TOC in the nav document.
The spine includes an ordered list of all the contents in the book, and it should also include an itemref for the List of Figures or List of Tables xhtml doc if one is present in the EPUB.
