In recent years university presses have undergone some significant changes, such as expansion of their scope to include materials
that may have appeal beyond the scholarly market. This article investigates, through the use of a survey of university libraries,
the acquisition of university press products by libraries. In general, recent years have been changes in the relationship
between university presses and libraries that have resulted in fewer items being purchased by the libraries. 相似文献

PUBLIC AND ELITE ATTITUDES TO ENVIRONMENTAL ISSUES 总被引：1，自引：0，他引：1
This paper puts the environment into perspective. Politiciansand commentators see the environment as yesterday's issue, forgettingthat the core of environmental activists is still double thelevel of just five years ago. International comparisons stretchingfrom Poland to New Zealand are made, examining the public'senvironmental behavior, attitudes and values. Using Great Britainas a case study, detailed comparisons are made between the attitudesof the general public with journalists, the financial community,captains of industry, and Members of Parliament and the latterthen compared with Members of the European Parliament. The publicis demanding action by companies and by governments on environmentalissues and has little faith in either to take corrective action. 相似文献
