Entity Reference Views are a great way to make life easier for Drupal content creators.

Normally, when people create content on your site, each field is very plain. However, Entity Reference Views allows you to provide far more information. For example, instead of just showing a list of users, your content creators can browse through a list of names, photos and personal details.

Both Views and Entity Reference are now part of the Drupal 8 core. This made using Entity Reference Views in Drupal 8 much easier.
