I bought this for a friend's son who is taking on A Level politics, but also ended up delving in myself. It's a great overview of liberalism from inception to the current vogue of "Clegging Out". If you're in the midst of study, or just want a snap shot of how liberalism has come to pervade, then Scheuber's quick guide is essential. If you're really pushed for time, there's even a 'liberalism in one minute' snapshot. Highly recommended.
