Good-quality resources for all levels of Spanish - if you've never been there, it's between South Ken and Notting Hill Gate. You should be able to make an appointment and have a nose in the library or buy resources in person. They usually represent themselves at language learning conferences and are always approachable and friendly! They offer dvd/video rental to teachers via post and have a long list of films and docs covering practically any topic/area you'll need.
Lot of other information regarding T and L in Spanish, including courses (here and abroad) and the odd competition - would like to get our lovelies more involved in these sorts of things (we've lots to offer! Don't laugh!), what do you think?
The resource publication put together by FLAs (Acti/Esp.) has just got snazzier and glossier and more colourful! I think you can get a copy by sending in stamps to cover costs (check site) and a version is also available online. Tecla is an electronic magazine that has a vast range of readings and activities, probably more suitable for our native speakers and more advanced learners of Spanish.
