More or Less Together (Waaldijk et. al.)

Kees Waaldijk (Leiden University) has edited a comparative survey of legal consequences attached to marriage, cohabitation and registered partnerships for different-sex and same-sex partners. It's a comprehensive study of nine European countries, that brings to light lots of interesting and sometimes unexpected patterns. One fascinating conclusion: even 'traditional' marriage (if you'll forgive the expression) means lots of different things in different countries. The entire report is available online here.
