The solution to inaccessible documentation can be as simple and low-tech as making a better index… With proper indexing, ten per cent more effort will double the accessibility of information.
A well-crafted, interactive index provides an alphabetical collection of links to topics, concepts, and relevant names and places within a document or collection of documents. As such, it provides a way of navigating content that other methods such as tables of contents, bookmarks, browsing and search, cannot.
In order to meet all of the ONIX Code List 196 accessibility criteria, ebooks need to include an index with “direct (eg hyperlinked) access to uses of the index terms in the document body.”
