Special Project: Case Studies on Sustainability for Digital Resources

这个特别项目开发了两个关于数字资源可持续性的案例研究，特别关注科学。第一个案例研究的主题是一个名为ebird的在线资源，由康奈尔大学鸟类学实验室运营。该网站依靠专业和业余鸟类观察者的志愿贡献来收集鸟类丰度和分布的数据，并以其对用户的高度关注和利用各种收入策略而闻名。第二个案例侧重于NSDL中学途径，这是一个有趣的案例研究，因为他们的领导人积极和创造性地参与制定新的可持续发展战略。该研究分析了不同的可持续发展战略和收入模式的成功和挑战，并指出了支持在线资源的最佳实践。

This special project develops two case studies on the sustainability of digital resources focusing specifically on the sciences. The subject of the first case study is an online resource called ebird, operated by Cornell University's Lab of Ornithology. The website relies on the volunteer contributions of professional and amateur bird watchers to amass data on bird abundance and distribution, and is notable for its sharp focus on users and for utilizing a variety of revenue strategies. The second case focuses on the NSDL Middle School Pathway which is of interest as a case study because of the way their leaders have actively and creatively engaged in developing new sustainability strategies. The research analyzes the successes and challenges of different sustainability strategies and revenue models, and point the way toward best practices for supporting online resources.
