The Canadian Research Knowledge Network will cancel a national license agreement for the American Chemical Society's Web Editions and Legacy Archives products.
Here's an excerpt from the press release:
Termination of the CRKN-ACS license will take effect at the end of 2013, at which time participating libraries may choose to contract directly with ACS or implement alternate arrangements. . . .
Under ACS's new pricing, costs for participant libraries will be determined solely by usage, using the average number of full-text downloads from the most recent three years, and with participating institutions organized into usage bands. Any growth in usage that would move a participating institution into a higher usage band would result in a prohibitive price increase that could double or triple the cost of the ACS content. This pricing regime represents a huge financial risk for those libraries that are most committed to promoting ACS resources, and will penalize those who are most successful in integrating ACS content into new web- and mobile-based discovery and access systems that are used increasingly by university researchers and students.
