Current Situation and Countermeasures of Book Purchase Imbalance in Engineering College Library

Currently,book purchase imbalance arises in the process of literature resources construction in some engineering college libraries.Namely,the proportion of social science books is higher than natural science books,which can not meet the needs of science and engineering readers.The main reason for the imbalance is the inherent higher proportion of social science books in the publishing market and inadequate natural science books provided by book sellers.Procurement staff of the library collection should pay close attention to the annual percentage change in collection books,reasonably regulate and control the ratio of natural sciences and social sciences books,gain multi-channel access to the original bibliographic data;Besides,strictly enforce textbook contracts,punish penalties for breach of contract,and participate in National Book Fair on-site procurement.
