# NotebookLM Folders and Collections A collection is a folder of notebooks. Kortex shows your Gemini Notebook (formerly NotebookLM) collections on the home page, and lets you file the notebook you are in without leaving it. The Gemini Notebook home page with a Collections from Kortex row above Recent notebooks ## Why use collections here? A collection works like a drawer in a filing cabinet. Put all your thesis notebooks in one drawer, your work notebooks in another. You find them with one click. ## Your collections on the home page On the home page, a row called **Collections from Kortex** sits above **Recent notebooks**. Each card is one collection. It shows the collection's name and how many notebooks are in it. - If you have a lot of collections, a button at the bottom shows more of them. **Show less** hides them again. - Click **Hide** next to the title to tuck the row away. The button then says **Show**. Kortex remembers your choice. - If you have none yet, the row says so. You make collections in the Kortex dashboard. See [Collections](/docs/collections). ## How to open a collection 1. Go to the Gemini Notebook home page. 1. Click a collection card. 1. You see only the notebooks in that collection. If it has smaller collections inside, they show first. 1. Click a notebook to open it. 1. To go back, click **Collections from Kortex** at the top. One collection opened, listing just its notebooks with a way back at the top ## How to rename or delete a collection 1. Move your mouse over a collection card. Three dots appear in its corner. 1.
