> Save the products you use again and again, sort them into collections and add them to any room. Plus what happens to rows in your projects when you change a library product.

The products library keeps the products you use again and again, with their photos, specs, prices, files and alternatives. Save a product once, then add it to any room in any project. It's under **Products library** in the sidebar, shared by your whole workspace.

![Hovering over the sofa row, clicking ⋯, choosing Save to products library and selecting a collection, with Save to library highlighted](https://densy.io/images/help/en/how-to-use-the-products-library/save-to-library.mp4)

## Save a product from a room

1. Hover over the product, click ⋯ (Options) on the right of the row and choose **Save to products library**.
2. Click **Select** next to the collections it belongs in, or leave them all unselected. No collection yet? Click **Create new collection**.
3. Untick any **Alternatives** you don't want to keep.
4. Click **Save to library**.

The library gets its own copy of the photos, files, specs and prices, and the row stays linked to it (see below).

To save several products at once, tick their rows' checkboxes, click **More** and choose **Save to products library**.

## Add products straight to the library

Open **Products library** and click **Add new product**:

- **Product:** fill in the details yourself.
- **Product from URL:** paste the product's link and click **Fetch details**.
- **Products from spreadsheet:** import a whole list at once.

If you have a collection open, new products go into it. The clipper saves into the library too: see [How do I install the Densy Product Clipper?](https://densy.io/en/help-center/how-to-install-densy-product-clipper-extension)

## Sort products into collections

Collections are your own shelves, such as *Bathroom fittings* or one per supplier. A product can be in several.

1. On the **Products library** page, click **New collection**.
2. Name it and click **Add new collection**.

Products without a collection are under **Unorganized products**: hover over one, click ⋯ (Options) and choose **Add to collections**, or use **Organize all to collections**. To move a filed product, open it and change **Collections**. Deleting a collection doesn't delete its products.

## Edit a library product

Click a product to open **Edit library product**, change what you need and click **Save library product**. The **Internal note** is never shown to clients, and **Attachments** holds spec sheets or quotes.

- Library prices have no currency: a project shows the same number in its own currency.
- **Update details from URL** reads the shop's page again and shows what changed before you save.

To delete one, hover over it, click ⋯ (Options) and choose **Delete**. Rows already in projects keep everything but stop being linked. To give a library product alternatives, open it and click **Add alternative option** at the top.

## Add a library product to a room

1. Under a section, click **Add new section item** and choose **Product from library**.
2. Pick a collection at the top, or stay on **All products**, and click **Add product**.
3. If the product has alternatives, untick the ones you don't need in **Choose alternatives to add** and click **Add to room**.

To add a library product as an alternative to an existing row, use **Alternative from library** in the row's ⋯ (Options) menu.

## What happens to rows when you change a library product

A row added from the library, or saved to it, stays linked to the library product. It shows **Library** next to its status.

**Its specs are locked in the project.** The name, dimensions, materials, supplier, prices and other specs come from the library: click one to choose **Edit in library** or **Unlink and edit here**. Quantity, notes, status and the client's decision stay editable.

**Changes reach projects only when you confirm them.**

1. When you save a library product that's used in projects, **This product is used in projects** lists the rows that don't have your change yet.
2. Every row starts ticked, except ones the client has approved, so an agreed spec isn't changed by accident. Untick the ones you want to leave out and click the update button at the bottom, or click **Not now**.
3. Rows you skip show **Library update**, and the room offers **Review updates** at the top.

An update brings in the library's specs, prices, photos and files. Alternatives you add to the library product later don't reach rows already added.

To stop a row getting updates, choose **Unlink from products library** in its ⋯ (Options) menu. It keeps everything, but can't be linked again. A row also unlinks when someone changes a locked field or deletes the library product.

Teammates with the Project member role can use library products, review updates and unlink rows, but can't change the library itself.
