Most of the "history" of the craft beer era was recorded in industry periodicals like All About Beer or local newspapers. As print journalism and beer periodicals has ceased operations, online article sites (e.g. Good Beer Hunting), podcasts, and Twitter have become popular means for sharing information. 

Depending on your topic, you will use several different types of source for researching the micro or craft brewing era. These include popular periodicals, websites, social media communities, and articles written by bloggers. While some still send e-newsletters, breweries are increasingly using social media to tell their own stories and histories on Twitter, Instagram, and Facebook.

Websites change or disappear without notice. The Internet Archive helps save that information. It includes links to websites, images of labels, audio and video interviews and brewery tours, podcasts, and tv news segments.
