This article is about Scratch libraries. For the general programming feature, see Library.

Libraries are sections in project editors were the user can select an example sprite or background. In Scratch 1.4, some sprites included in the library had premade scripts. Libraries are useful for those who either cannot create or do not have media to upload.

The sprites library of Scratch 3.0.

Tutorial Library

What the tutorials library looks like.

In Scratch 3.0, the tab for tutorials was moved to a new library called the Tutorial Library. It is linked from a button at the top bar with a lightbulb. There are a total of 25 tutorials there, which if clicked, returns to the project editor and opens a Project Tutorial with a video that shows the tutorial. Pressing the arrow takes one to a step-by-step instructions area, with a "More Things to Try" at the end.

Extensions Library

The extensions library is where all of the extensions are located. Extensions include PicoBoard and Lego WeDo. There are also many other hardware extensions. Scratch 3.0 added many more extensions.
