That most traditional of all the UK breweries, Samuel Smith's have finally joined the Internet age and invested in a website. Don't expect anything too spectacular though, this is Sam's we are talking about. For locations about their pubs - they run around 305 of them there is a website featuring a map here.
It does come as surprise the number of pubs they actually run in London and a lot of them are classics such as Ye Olde Cheshire Cheese and the Princess Louise.
For unofficial news of Sam's there is a website here.
As well as the Tadcaster Brewery, Sam Smith's also own the All Saints Brewery, Melbourn Brothers in Stamford, Lincolnshire and this has quite a good website.
