The Library is Mesa’s built-in legal content hub. Browse jurisdictions, regulations, and collections; annotate as you read; and pin the content most relevant to your practice so it’s always one click away.

​
Browse the Library

Open the Library tab from the sidebar. Your organization may have already pinned jurisdictions and collections for you; otherwise, click Browse the full library to explore everything available.
Use the search tool to look up content directly, or navigate manually to the jurisdiction you want to read.

​
Read and annotate

Inside any content area, select text to apply a highlight or add a note. Your annotations are collected under My annotations, which you can open from the main Library page.
The same highlight-and-note flow works inside PDF documents too, such as files in a Vault. Select text directly in the PDF viewer to pick a highlight color or attach a note; the annotation is anchored to that exact page and passage, so it stays put as you scroll or zoom.

Plain-text documents, including web pages and other markup files that Mesa reduces to text, show their text as readable prose, so you can highlight, annotate, and search inside them the same way. Code and structured data files (JSON, XML, logs, and source code) show in a monospaced view instead. While reading, you can also select Search only this section to search within the current content page.
Use Search only this section when you’re already inside a regulation or collection and want to find a provision without leaving your reading context.

​
Pin jurisdictions and collections

Pinning keeps your most-used content at the top of your Library. You can pin from three places:
  • Inside any content area, click the star icon in the top-right.
  • On the main Library page, pin items Mesa surfaces where you left off.
  • On your Customization page, manage pinned jurisdictions and collections directly.
Owners can pin content for the whole organization; see Organization customization.

​
Resume where you left off

When you return to the main Library page, Mesa reminds you where you stopped reading, so you can pick the content back up without searching for it again.
