Book Square Icon

Q: When should I use it instead of a similar icon?

Use it for knowledge base tiles on a workspace home or an app launcher, beside other framed tiles; and the Guides row in an iOS style settings list, where every row starts with a framed glyph. For an inline Continue reading control on a library card, use the Book Open icon. For documentation links in a site header or footer, use the Book icon. For a help menu in an app header with docs and contact options, use the Question Circle icon.

Book Square icon FAQ

What does this icon show?

Open book inside a rounded square, for reading apps, knowledge base links and library sections. Typical uses: knowledge base article link, reading app tile and library section header.

When should I use it instead of a similar icon?

Use it for:

Knowledge base tiles on a workspace home or an app launcher, beside other framed tiles

Which styles does it come in?

4 styles: Outline, Solid, Duotone and Filled. Every style is drawn on the same 24 by 24 grid and installs as its own file, so you can switch styles without touching the layout. An animated variant also plays a short animation on hover, or whenever your code starts it.

How do I install it with the shadcn CLI?

Copy the install command from the panel above, in the style you want, and run it in your project. The shadcn CLI adds the icon as a React component that you import and render like any other. It draws in the current text color, so your text color and size classes style it. Icon installs need a ReUI Ultimate license.

What icons go well with it?

When was it added?
