Modern usage and definitions
In Europe and Latin America, liberalism means a moderate form of classical liberalism and includes both conservative liberalism (centre-right liberalism) and social liberalism (centre-left liberalism).
In North America, liberalism almost exclusively refers to social liberalism.
In my country, the formerly centre-right, now just right "the market will take care of it" party calls itself liberal ever since the 50s.
