![Copyright lobby targets "Pirate Bay for textbooks"](https://cdn.afterdawn.fi/v3/news/bookabooka_logo.jpg)
Despite these "small" differences between TPB and Bookabooka, The Finnish book publishers' association (Suomen Kustannusyhdistys) is convinced that Bookabooka is breaking the copyright legislation and threatening their business. Annual school textbook sales in Finland were worth more than €100M in year 2007.
TTVK demands (PDF, in Finnish) that the service must be shut down by Friday this week or they'll sue the company. Bookabooka's founders have already stated that they wont respond to the threats, but instead will keep the service running.
