Scottish Law Commission
Excellent revised site with full details of the programme of the Commission (official law reform body) together with full text of all recent reports and papers and many of the older copies too: often a very fruitful start for research.

This long-established site has now fallen into disrepair – may still be worth a look among the cobwebs if you can't find what you're looking for elsewhere.

Contains synopses of articles (and occasional free articles), usually with a Scots law bent, in this thrice-yearly, high quality, academic journal.
This large site contains information about all aspects of the Scottish legislature including the texts of Bills and explanatory notes, the official Parliamentary reports and webcasting of the Parliament: for the text of Scottish legislation: go to www.legislation.gov.uk/browse/scotland.
