The Writers' and Artists' Yearbook is one of the 'bibles' for all matters to do with writing. An invaluable source book for listings of magazines, publishers and agents for over 100 years. Each year, it also contains excellent articles and advice from big name authors - from writing a synopsis to the submission letter. There is also a dedicated issue for children's writers.
The publisher, A&C Black, is running a short story competition with the theme of 'compulsion'. Closing date is February 14th and length is 2,000 words maximum. See full details on the Writers' and Artists' website.
