The London Book Fair is the trade show for publishers, agents and booksellers. Now in its 47th year, anyone in the book business anywhere around the world finds themselves heading for London in April. During the three-day event at London’s Olympia, held this year between 10th and 12th April, over 25,000 people connected with the publishing industry will pass through its doors. The question is: should you be going? Is there a business-case for writers making the trip?
