Library Journal has published "Periodicals Price Survey 2008: Embracing Openness."
Most of the narrative discusses open access developments. The news on toll-access serials remains grim:
Prices of subscription-based journals increased nine to ten percent in 2008, driven by an extremely weak dollar. Non-U.S. titles in the humanities and social sciences increased even more (11 percent), because publishers in these disciplines tend to price in native currencies, driving U.S. prices up when those currencies are converted to dollars. The sciences, on the other hand, are dominated by large European publishers that price in U.S. dollars, reducing the volatility of prices and keeping price increases in foreign scientific journals under nine percent. Given the continuing slide of the dollar, expect increases in 2009 to approach ten percent overall.
As usual, the article includes detailed tables packed with serials cost information.
Average subscription prices in some high-ticket disciplines include: Chemistry, $3,490; Physics, $3,103; Engineering, $1,919; Biology, $1,810; and Technology, $1,776; and Astronomy, $1,671.
