之前有在看“Networks, Crowds, and Markets: Reasoning About a Highly Connected World”这本书，导致对这门课有了错误的预期。课程比书简单很多，主要是围绕着一些基本概念进行阐述的，讲得很细，会从定义、具体实例等多个方面反复讲述，而且跳过了所有复杂的证明，高中以上的听懂应该是没问题。真的就像课程预备知识里写的那样，高中代数再加一些基本的概率知识就可以了。作业中没有编程、设计与论述题，都是关于概念的选择题。
作为Social and Economic Networks的入门课程应该是不错的选择，而且老师们很贴心的在课程最后列出了其他相关公开课、书籍的名称和网址，方便大家进一步进修。
First, there are other MOOC focusing on social networks. A partial list is:
- Networked Life, by Michael Kearns, https://www.coursera.org/course/networks
- Social Network Analysis, by Laura Adamic, https://www.coursera.org/course/sna
- Social and Economic Networks: Models and Analysis, by Matthew Jackson,https://www.coursera.org/course/networksonline
Second, there are several books, at various levels of difficulty that address some of the topics from our course, and often address other topics too:
- The online textbook we used for our course, Networks, Crowds and Markets by David Easley and Jon Kleinberg, available at http://www.cs.cornell.edu/home/kleinber/networks-book/, includes both additional topics that we did not cover in the course and more advanced material (in the appendices) on many of the topics that we did cover in our MOOC.
- The textbook Social and Economic Networks, by Matthew Jackson, is written at a more advanced level than our book and it covers network formation, a topic that we only touched on in our MOOC.
There are many other interesting books on networks including:
- Six Degrees: The Science of a Connected Age by Duncan Watts
- Linked: How Everything Is Connected to Everything Else and What It Means for Business, Science, and Everyday Life, by Albert-Laszlo Barabasi
- Connections: An Introduction to the Economics of Networks, by Sanjeev Goyal
- Networks: An Introduction, by Mark Newman.
