摘　　要：服务等级协议(Service Level Agreement,SLA)是服务提供商与用户之间签订的一份合同,合同的内容主要包括服务的内容、服务双方的职责和义务以及服务定价等相关内容。用户与提供商签订SLA,就能获得SLA中规定的服务质量,或在没有获得规定的服务质量时,便能获得提供商给予的赔偿,使服务质量有保障。在图书馆云服务中,图书馆信息服务的参与方相比较传统的图书馆信息服务的参与方数量有所增加,在其内容和服务过程的角色中也有所不同。文章针对图书馆云服务的特性,研究了基于SLA的图书馆云服务成本计算模型。Service Level Agreement （SLA） is an agreement about the Quality of Service between the Service Provider and Service Customer. It aims at defining the details of the service contents, responsibilities and obligations, service price et al. So a good quality of service can be supplied for the customer if the SLA is signed, and, if the quality of the service is not reached the level of the customer required, compensation should be supplied by the service provider. Compared with the traditional library information service, the quantity of the participants in library cloud computing service gets increased, and at the same time , the service contents and service process are also different. From the above reasons, according to the characteristic of library cloud computing service, this paper does some research about the cost model of library cloud computing service based on SLA.
