Abstract

Indexes in ebooks can be ‘active’, with hyperlinks into the text. Should these links go to the page, paragraph, line or word level? This is a complex question, but the main concern may be the user interface in ebook reader applications. In this last article of a four-part series, Mary Coe and Jan Wright report on their investigation of how active ebook indexes are handled by applications on smartphones. They conclude that smartphone applications perform reasonably well but do not handle all levels of locator specificity with precision and that small smartphone screens can lead to problems with index display and use. They also conclude the series with a summary of their findings across all ereading applications and devices.
