The Incorporated Council of Law Reporting (ICLR) in the United Kingdom, the people who bring us the authoritative and official Law Reports, have their very own YouTube video channel.
Videos include interviews with the Law Report editors, a history of the ICLR, a video on the process of how a case goes from trial to official report, and a brief introduction to case law research using both online databases and hard copy reference works.
And check out their wonderfully produced video A Tale of Two Citations:
"This short featurette featuring two barristers. One of them serenely competent and well-prepared with the proper law reports to support her case, and the other rather less well-organised, chaotically downloading and printing transcripts from the internet, much to the judges irritation".
