SStreams is primarily a directory of links related to the use of technical and scientific software. The top categories correspond to the software application. Lower-level categories are almost identical for each line of software. They are designed to help you find the resources you need.
Horizontal navigation is made possible by links pointing to a similar category for other software.
By browsing the directory horizontally you can identify the software applications most appropriate to your needs. See the Navigation page for a detailed description of the directory features. Using SStreams is entirely free. You can even access an advertising free version of the directory. If you find this resource useful, we would be most grateful if you would be willing to make a small donation to support our efforts.
