Wikibooks

摘要

Colleges, universities and high schools have long heard the complaint about the cost of textbooks. Basically, as soon as some textbooks are published they are out of date. A book on law, for example, changes depending upon the legal structure of the state. A work on science changes as new items are discovered or old beliefs are debunked. A lot of funds are spent - either by the school board or by the student - in purchasing textbooks that may be used infrequently or may be soon out of date. Given the nature of Web 2.0 technologies and beliefs and the inherent problems of print textbooks, Wikibooks has grown.
