Here are a few international prizes that literary translators associations can apply to for their initiatives.
Every year the London Book Fair awards the Best Literary Translation Initiative (the rules of the contest are published on the LBF website: click on the menu bar item What’s On and then Awards).
And if you are a FIT member:
FIT (International Federation of Translators) Prize for Best Website
The competition is open to any FIT member in good standing or any recognized branch, chapter, regional group or section thereof is entitled to nominate its website for the Best Website Prize.
A Certificate of Merit will be awarded to the website which is considered to best promote the professional image of the translator and/or interpreter in terms of quality, presentation and relevance.
FIT (International Federation of Translators) Prize for Best Periodical
The competition is open to any journal published by any FIT member, or any recognized branch, chapter, regional group or section of such an organisation.
