This confirms Elsevier's status as the most avaricious publisher, accounting for more than one-third of Finland's overall subscription costs. Wiley comes in a distance second at 10%. Many academics, particularly in mathematics, have come to boycott Elsevier's journals due to it's extraordinarily high prices and "all-or-nothing" subscription model. However, due to NDAs that Elsevier forces libraries to sign, confirmed numbers were previously very rare.

Some more information on the boycott appears in [1] and at Tim Gower's blog [2].
