A material library is a collection of materials and related assets. Some libraries are provided by Autodesk, and others are created by users. You can create libraries to organize your materials. You can also share libraries with other people on your team, and use the same libraries with Autodesk Inventor and AutoCAD to support the use of consistent materials.
The libraries supplied by Autodesk are locked, as indicated by a lock icon. Materials in a locked library cannot be overwritten or deleted. You can copy materials from a locked library to unlocked user-created libraries, where materials can be overwritten or deleted. In the following figure, the AB Project Materials library is an unlocked user-created library.

Libraries can be sub-divided by adding categories and moving materials into the categories. An Autodesk-supplied library contains many categories of materials organized by type, such as Concrete, Metal, and Glass. User-created libraries and categories can reflect different methods of organization, such as project names or usage. In the figure, the AB Project Materials library contains a Construction category.
To work with libraries, access the Material Browser by clicking Manage tab
Settings panel

| 3 | Show/Hide Library button and Library settings menu : These 2 buttons let you modify how libraries, and their materials, are displayed in the Material Browser window. Click the Show/Hide library panel button to show or hide the display of the library tree. You may need to hide the display of the library tree to provide more space for viewing library materials. Use the library settings menu options to filter the display of materials presented in the library materials list. |

Material Browser toolbar: Provides controls to manage libraries, create new or duplicate existing materials, or open and close the Asset Browser. |
| 7 | When a material is selected in the library list (left pane), this right pane displays the tabs (assets) associated with this material. Click the tabs (for example, Identity or Appearance) to view the properties and assets of the material. When viewing materials in libraries, properties are read-only. |
Common Material Browser Tasks
To add a material to the current project, first find the material in an existing library, then use one of these methods:
- Double-click the material in the library list.
- Drag-and-drop the material from the library list into the project materials list.
- Right-click the material Add to Document Materials.
- Select the material in the library list, and then click the Add button
located to the right of the material. 
To copy a material to a library, use one of these methods:
- Drag-and-drop the material into the library.
- Right-click the material Add to <Library Name>.
If you copy a material to a library where another material of the same name exists, you are prompted either to overwrite the version in the target location, or to keep both. If you keep both, the material name of the material you are copying is appended with a number; for example, Porcelain, Ivory(2).
