The library channel is often underappreciated as a key part of a publisher’s business strategy. In an age where publishers are constantly seeking new revenue and marketing opportunities, presence in the library—digitally—can yield significant growth. This paper examines the library channel, its business model based on library lending, the performance of eBooks and audiobooks across all subjects, and consumer reading behavior. Digital Book Clubs, a relatively new phenomenon, are also defined and illustrated with examples demonstrating the library’s valuable role in increasing discoverability and ultimately sales. 相似文献

This paper proves that social media use can contribute in important ways to employability outcomes. Specifically, results from a survey of 196 recent graduate students in China indicate that social media use is positively related to employability skills. Internship effectiveness serve as a mediating mechanism through which social media use affects employability skills. Zhongyong has a moderating effect on the social media use-internship effectiveness relationship. In addition to the direct moderating effect, Zhongyong is found to moderate the indirect relationship between social media use and employability skills. We discuss implications of these results for research and practice. 相似文献

ABSTRACT The past 20 years have seen major efforts to extend and reform the system of general education in Spain. Some of the most important reforms are contained in legislation passed in 1990. These developments have direct relevance to the reform which has also been taking place in the system of special education. Official policy is that integrated provision should be available in all schools, but in the short term the system has set itself an initial and more limited objective. 相似文献
