Users are always right

Yesterday, I received a book Users are always right by Dr. Cheng Huanwen. The book collects all blog posts by Dr. Cheng about the theorem "Users are always right" and related blog posts by library scholars and librarians in China. Because the book also includes one of my blog posts at Sina blog (Bookworm: http://blog.sina.com.cn/guben), Dr. Cheng sent me three copies for my own collection and for the collection of the National Library of China. I think the book is interesting, not only because of the new topics, but also because it is very new in China to publish a collection of blog posts.
