How do I get more Reformer Pro libraries?

There is a huge selection of Reformer Libraries available at here.

You can also choose to buy more libraries to use in Reformer or Reformer Pro whenever you like. You can do this by clicking on the ‘Buy More Libraries’ panel in the libraries section of the plugin. This will be found at the bottom of your library list in the plugin. To access this, click on the grey panel with the name of the library.
