Electoral systems

I've been reading up on voting systems and "proportional representation". The BBC has a nice article on what other countries do. If you are interested in a bit more detail about voting systems from an academic who has thought about them a lot, see Denis Mollison's article about STV and his paper for publication in the RSS's journal.
Denis, a statistician at Heriot-Watt University, recommends the STV system with multi-candidate constituencies. Its implementation would require a computer.
[If you're interested in more exotic methods that require not only a computer but also the use of randomness, then please see Probabilistic electoral methods, representative probability, and maximum entropy by Roger Sewell, David MacKay, Iain McLean.]
