Authoring application by Apple Inc
iBooks Author (iBA) was an e-book authoring application by Apple Inc, released in early 2012, only available for macOS, and discontinued in 2020.[2]
Overview
Documents created by iBooks Author could only be sold for a fee if they are accepted by and distributed by Apple,[3][4] but authors also had the option to distribute their work elsewhere for free.[5]
It allowed many aspects of a document to be edited in WYSIWYG fashion, including text, fonts, colors, foreground and background images, interactive widgets, and charts.[6]
iBooks Author was discontinued on July 1, 2020, with Apple suggesting Pages as a replacement.[7]
