Google Fonts is amazing collection of free fonts. 916 font families just waiting for you. You can download them all in one zip file totalling 407 MB.
I haven’t updated my Google Fonts collection since 2015. Today I added the updated collection to my hard drive. Over the course of four years, Google has added 217 font families.
Wow! What are in these 217 font families? A LOT. Seriously. Here’s a screenshot of just the first 31:

This screenshot is just the listing in my font management program, Font Explorer X Pro. This program has lots of great features, like being able to print out previews of a collection of fonts. So I made a handy PDF preview.
Preview all Google Fonts added during 2015 to 2019 in a PDF
Here’s a handy 87-page PDF containing a preview of all the Google Fonts added in the last four years.

And if you’d like a simple text list of the names, this is the complete list of Google Fonts added between July 1, 2015 and June 4, 2019:

Ah, take a breather.
There are so many fonts already in Google’s collection, that they could just sit back and relax. I’m glad that Google continues to add fonts.
