# Library

> Keep a file once on the school's shelf, with folders and tags.

**Library** is the shelf of files you keep once and reuse. A teacher sees the school's items and their own; owners and admins see everything.

Items are grouped by folder. Use the filters to narrow the list by tag, subject or level.

Choose **Edit** on an item to change its title, folder, subject, level and tags. Separate tags with commas. Choose the archive button to take an item off the shelf. A teacher can edit and archive their own items; the school's items are for owners and admins.
