Essay on open access process: chronology and compared data on profit:
How profitable publishing Science can be, is illustrated by the following figures: in 2011 Elsevier asked $ 7089 for a subscription to Theoretical Computer Sciences (source: American Mathematical Society). That same year Elsevier also made a profit of £768 million on a turnover of £ 2.1 billion, a margin of 37.3%. 78% of those sales came from selling subscriptions to scientific journals. Compare this with a margin of 24% in 2011 for Apple, the highest profit ever in the history of this company. Another example: during the last 6 years, average prices for access to online content from 2 large scientific publishers have increased by an incredible 145%.
