There is a good ten minute interview with the great Spanish writer Ana María Matute at Revista de Letras where she talks about her writing and her life. Of particular interest, she says she was the first to use children in fiction in Spain. Her contemporaries did not. Only after she gained success did they also do it. Considering how much she writes about children she probably is talking with some authority, although, I would like a little more confirmation. Fortunately, you can read her works in English. Many have been translated.
The video is also a lesson in what not to do when interviewing an author. While author interviews can be a little boring, the producers put such long transitions between ideas, complete with Jazz and hazy graphics, that it got a little boring waiting for her to speak.
