Information
Edinburgh's tourist office website is a good source of pre-arrival info and worth consulting when you’re in town since there is no longer an official Tourist Info centre.
In its absence a couple of unofficial Tourist Information centres-cum Scottish-made craft shops have sprouted around St Giles Cathedral, including Source (this entry’s map location) and another at 249 High Street.
The List
The List, a bi-weekly arts and entertainments magazine, is the most useful independent what's on guide.
Though The List has a great website, perusing a paper copy, bought from a local newsagent, is hard to beat. Foodies should pick up it's annual magazine-format Eating & Drinking Guide.
