VitalSource Bookshelf vs zyBooks

VitalSource Bookshelf is an app for reading and studying eTextbooks and other digital learning materials on Android, iOS, macOS, web, and Windows. Its study tools include highlighting, notes, flashcards, bookmarks, citations, search, and read-aloud. Users can download titles in desktop or mobile apps for offline reading and study, and notes and highlights sync across registered devices. VitalSource says the app supports assistive technologies for people with visual, hearing, or mobility impairments. It can be installed on up to two computers and two mobile devices at a time. Integrations support learning management system access, single sign-on, roster sync, and grade pass-back. The app is free to install at free, while eTextbook content may require purchase or an active license; pricing is also listed on request. For offline access to a lifetime-access eTextbook, download it within 180 days of purchase. VitalSource says assignments and library filters are being deprecated as part of a Bookshelf experience update.

zyBooks is interactive digital courseware designed as an alternative to textbooks in STEM courses. Instructors can add custom content, create sections and chapters, and set course content and pacing.

Security course materials include labs for practicing malware creation, network analysis, and vulnerability assessment. The maker describes accessibility against WCAG 2.2 A/AA, Revised Section 508, and EN 301 549, and offers accessibility modes and chapter PDFs. Access is by paid subscription, with a free evaluation available to instructors.
