This article reviews available cost-effective options libraries have for updating and maintaining pathfinders such as subject guides and course pages. The paper discusses many of the available options, from the standpoint of a mid-sized academic library which is evaluating alternatives to static-HTML subject guides. Static HTML guides, while useful, have proven difficult and time-consuming to maintain. The article includes a discussion of open source database-driven solutions (such as SubjectsPlus, LibData, Research Guide, and Library Course Builder), Wikis, and social tagging sites like del.icio.us. This article discusses both the functionality and the relative strengths and weaknessess of each of these options.
Corrado and Frederick have put together an excellent overview of free and open source subject guide software for libraries in their article, Free and Open Source Options for Creating Database-Driven Subject Guides. It’s a good place to start if you are looking for a package to use for your library.
