When improving a web presence, today's libraries have a choice: using a free Web 2.0 application, opting for open source, buying a product, or building a web application. This article discusses how to make an informed decision for one's library. The authors stress that deciding whether to use a free Web 2.0 application, to choose open source, to buy a product, or to build a web application is closely tied to a library's specific needs and resources. They suggest to keep an open mind toward each option, and think through the implications carefully before committing to any solution.
