I have to admit I'm a software (and especially a font) junkie. So when I ran across a web article explaining how to add the Google font library to Suitcase Fusion I had to give it a try. According to Extensis this is how you add Google fonts to your own Suitcase library:
Launch Suitcase Fusion.
Click on the File Menu, then click on Enable Google Fonts.
A new Google Fonts library is added to Suitcase and the font collection is automatically synced to your machine. Be patient as it takes some time to add the new fonts. The new fonts can be activated and deactivated like any other font in your Suitcase library.
To add new Google fonts click on the File Menu, then click on Synchronize Fonts. Any new fonts that Google has added to their collection will be downloaded to your computer.
Alternately, you can peruse and download individual font families. The Google Fonts webpage provides a simple sample of each font, notes the number of variations in each family and when you click on a sample block it takes you to detailed page of information includes a download button. At present, there are 999 font families to choose from and the site contains a number of options to narrow down your search for the perfect typeface. This is a tremendous free design resource that you should check out if you haven't already done so. Here's a link: https://fonts.google.com/
