3. Books
A book is the basic unit of content distributed in Handbook X. You compose content by adding sections (PDF, images, videos, web links, etc.) within a book.
3.1 Book List
The book list is the first screen displayed after login.
Display Items
| Item | Description |
|---|---|
| Book Name | Name and description of the book |
| Size | Total size of content in the book |
| Create Date | Date and time the book was created |
| Updated | Date and time the book was last updated |
| Number of Sections | Number of sections in the book |
| Owner | Owner of the book |
Sorting
Click on any column header to sort by that column. Clicking toggles between ascending and descending order.
Selecting Books
You can select books you own by clicking the checkbox. Multiple selection enables bulk operations such as batch removal. Checkbox-based multiple selection is performed in Edit mode (see the next section).
3.1.1 View Mode and Edit Mode
The book list is operated by switching between two display modes: View mode and Edit mode.
View mode (default)
Right after opening the book list, you are in View mode. The toolbar at the top right shows the following buttons and selects:
- Books to display: Filter the list by sharing status (see 3.1.2 "Books to display" filter)
- Size: Select that switches the cell size in grid view
- Sort: Select that switches the sort order
- List / Grid: Toggle between list view and grid view
- Access Code: Register an access code (see 3.7 Access Code)
- Edit: Switch to Edit mode
In this mode you can perform viewing operations such as clicking a book to open it or sorting by column header. Hovering on the right end of each row reveals Edit / Remove icons that act on a single book.
Note: The Books to display, Size, and Sort selects show the currently selected value as the button label. Clicking a select opens a dropdown whose header shows the section title (e.g. "Books to display").

Edit mode
Clicking the Edit button at the top right switches to Edit mode, and the toolbar changes to:
- Remove: Bulk-remove the selected books
- Transfer Owner: Change the owner of the selected books (see 3.6 Changing Book Owner)
- Export Section URLs: Export section URLs of the selected books
- Done: Return to View mode
In Edit mode, a checkbox appears at the start of each row, and you can select multiple books for bulk operations. Once at least one book is selected, N selected is shown at the top of the screen and the actions above become available.

Tip: The per-row Edit / Remove icons for a single book stay in View mode. Use Edit mode only when you want to multi-select for bulk operations.
3.1.2 "Books to display" filter
Use the Books to display select in the toolbar to filter the book list by sharing status.
| Option | Books shown |
|---|---|
| All books (default) | All books you own or that have been shared with you |
| Shared books only | Books that have at least one user share, group share, or access code share configured |
| Unshared books only | Books that have not been shared with anyone yet |
Tip: Use Unshared books only to find books you may have forgotten to share, or Shared books only to clean up existing sharing configuration.
3.2 Selecting a Workgroup
You can switch the displayed workgroup from the tab bar at the top of the book list.
- Click the workgroup you want to display in the tab bar
- Only books belonging to the selected workgroup are shown in the list
Tab order
The tabs are displayed in the following order:
- All workgroups (pinned at the leftmost position)
- Workgroups you own
- Workgroups you have joined
The original order is preserved within each group.
Horizontal scrolling for many tabs
When there are too many workgroups to fit, the tab bar scrolls horizontally.
<</>>buttons appear at the left and right edges to scroll the tabs- You can also scroll using the mouse wheel or touch panning
- The currently selected tab is automatically scrolled into view
Note: The tab bar lists every workgroup you have joined, not only the ones you own or manage. You can browse books belonging to workgroups you joined even as a Reader (per-book edit rights are still enforced by the individual sharing settings).
Note: Which books appear in a workgroup's book list — A workgroup's book list shows books that are shared with the workgroup as a whole (access-code sharing, group sharing, or user shares from an owner / admin / editor). Books that reach members only through direct member-to-member user sharing inside the workgroup are not included in the workgroup book list. In that case, the recipient member can still access the book as an individual share (statistics APIs continue to count all sharing paths as before).
3.3 Creating a Book
