About the Book Question Mark black outline icon

An open book shows two facing pages of ruled text lines, with a rounded speech bubble containing a question mark floating above the spine. It signals looking something up, FAQs, study questions and instructional help. Fit for knowledge base headers, help center menus, quiz and e-learning apps, library search pages and product documentation sites.

The bubble overlaps the top edge of the pages so the two elements read as one unit, and the text lines taper toward the outer margins to suggest perspective. A thin circle encloses the whole mark. Pair it with lightbulb, magnifier and graduation cap icons; keep it above 40px so the page lines stay distinct.

This is the black outline version of the book question mark icon: even, monoline strokes that stay crisp at small sizes and suit clean, minimal interfaces, wireframes and light backgrounds.
