What is the difference between SharePoint Document library and SharePoint List?

SharePoint Document Library :

1- SharePoint library is really for holding documents, files, and images etc. in similar way to how a regular folder on a shared network drive does. For this reason, libraries allow you to set up templates for common types of document and also give the option of version control so that you can track any revisions.

SharePoint List:

1- It is best thought of as mini-databases.

2- A list will allow you to store a number of items such as KPIs, tasks, events, staff details etc. in a similar way to how MS Excel or MS Access will.

3- The beauty of SharePoint's lists, is that you can make quick work of building a simple database (with its own, customizable, data entry forms) in a matter of minutes and without any coding. You can also choose which fields to include (title, reference number, status, date etc.) or create your own by creating a new content type and then adding custom columns to it.
