With all the features and graphics of the published books, the CD-Rom also offers a variety of other learning resources, to engage the reader and deepen research and reflection. Fully searchable texts, glossaries hyperlinked from the text, links to additional resources on the Web, chapter summaries, reflection questions, and research guides enhance the usefulness of the texts themselves and extend the readers knowledge and understanding. The widely used Libronix software also allows note taking, bookmarking, highlighting, and advanced searches.
