Library Journal has published "Reality Bites: Periodicals Price Survey 2009."
Here's an excerpt:
As waves of grim economic news wash over state and federal governments here and abroad, libraries of all types and sizes are bracing for budget cuts the likes of which have not been seen in three generations. Unlike most financial crises, this one is ubiquitous, with all but a handful of states in the red and getting redder. Globally, the meltdown is playing havoc with currencies, and the cost of journals priced in currencies other than the pound, the euro, or the U.S. dollar have skyrocketed. Severe losses in endowment revenue, which in the past insulated materials budgets to a degree, have left even larger and wealthier libraries facing cuts.
A number of librarians expect the budget cuts to be permanent; others say funds will rebound, but the recovery will take years. Even if the recession is less severe than feared, experts say not to expect relief before 2012. In journals parlance, that’s three renewal cycles from now—more than enough to stress publishers without deep reserves. For an industry that is already in the throes of reinventing itself, this recession will hit hard.
