Here is a list of tools in a few loosely defined categories relevant to science mapping:

· Science Mapping Tools

· Bibliometric, Citations, and Usage Tools

· Network, Tree, and Text Visualization Tools

· Utility Tools

The list is by no means comprehensive. I would like to beef up the content and maintain it as often as possible. If you have suggestions for new entries, please feel free to get in touch.
