Now of days there is not so much difference between social democrats and social liberals , especially since the rise of third way politics [en.m.wikipedia.org] , both are positioned on the center-left of the political spectrum [en.m.wikipedia.org] . This somewhat lengthy article might give some insight . [prospect.org]

The latter isn't an established political theory, unlike social democracy. Social Democracy is a theory of system of government and society, based not on extreme socialism but a mixed economy and directed to fair social and economic outcomes.

The word liberalism has been contorted badly by conservatives. Look at Neo-Liberalism, which had nothing to do with liberalism except to destroy it.

Please define what you mean, I have never heard of Social Liberalism to describe any political, governmental or social construct.

Social Democracy is a fusion of Socialism, and Capitalism, designed to guarantee basic human rights, and to see to it that basic needs are met, while still allowing for limited "free enterprise". Social Liberalism grew out of the eighteenth-century European Enlightenment, and is basically the idea that laissez- faire should apply to every aspect of life.(nowadays, it would be called 'Political Correctism' ). Social Democracy is designed to appeal to the masses. While Social Liberalism largely appeals to liberal-minded bourgeois, petit-bourgeois, and the 'intelligentsia'.

Probably none if Social Democracy is in practice by Social Liberals...without practitioners liberalism is a movement to change our fascist AmeriKKKa....partial Democracy exists in colleges and cities like NYC

I never heard of the latter.

I'll look it up.

Completely different
