Use the Network Book Scanner
📌 Requirements: Pressbooks Enterprise Network with the Content Toolkit enabled.
The Network Book Scanner, a feature in the Content Toolkit bundle, allows network managers to scan multiple, selected books on their network for common accessibility issues and broken links. It also displays information about the most recent accessibility and link checker scans performed on books on the network.
Institutional managers on Shared Networks also have access to the Network Book Scanner, but they only have visibility into and the ability to scan books that are assigned to their institution.
Scan Books
First, navigate to Administer Network > Books > Network Book Scanner. This brings you to the Network Book Scanner page.
In the Bulk Actions dropdown menu at the top and bottom of this page, you’ll find there are two kinds of book scans available: an Accessibility Scan or a Link Checker Scan. There is also a Combined Scan, which performs both scan types together (counted as two scans).
To trigger a scan, first locate the books you wish to scan. The Network Book Scanner page, by default, displays all books on the network alphabetically by title, but it can also be sorted in other ways. Click Word Count to sort books by highest to lowest, or lowest to highest number of words. Click Public to group Public or Private books together. Click Last Accessibility Scan or Last Link Checker Scan to sort books by those with the most recently performed scans of either type. If you are on a Shared Network, click Institution to sort alphabetically by the name of the institution the book belongs to.
For each book you wish to scan, click the checkbox on the left-hand side of the table (left of the book’s cover and title). Then, from the Bulk Actions dropdown menu (located both at the top and bottom of the page), select the type of scan you wish to perform on the selected books. Click Apply to trigger those scans.
This adds the scans to the queue for processing behind the scenes. A message is displayed here showing the scans in progress, updated as the scans complete. You can navigate away from this page while scans are in progress and return later. Once the scans you’ve triggered from this page have all completed, a “Book scan completed” message is shown on this page for the next 20 minutes.
⚠️ If you or another user (a book Administrator or Editor) triggers a scan from the Accessibility Report or Link Checker page of an individual book dashboard, and that scan is currently in progress, it is also counted in the progress message displayed on the Network Book Scanner page.
Examine Recent Scans
The Last Accessibility Scan column displays the date and time that a book’s most recent accessibility scan was completed, along with the user who initiated the scan. In the Issues column to the right, you’ll see the number of accessibility issues (including alerts of potential issues) flagged in the most recent scan. Clicking the number takes you directly to the book’s Accessibility Report page for more details.
Likewise, the Last Link Checker Scan column displays the date and time that a book’s most recent link checker scan was completed, along with the user who initiated the scan; this has its own Issues column to the right with the total number of potentially broken links found, a clickable number that takes you directly to the book’s Link Checker page.
Understand Scan Limits
During the free trial of the Content Toolkit bundle from February 10th through February 26th, 2026, networks have a daily scan limit of 20 scans, while individual books have a daily scan limit of 2 scans. Accessibility scans and link checker scans are each counted as their own scan. A combined scan counts as 2 scans.
When non-network manager book Administrators or Editors initiate scans from their individual books, this is counted towards the total scans used for the day within the network.
