Sites with links to reusable software components
To be included in this list, a site must have information pertaining to
reusable software libraries that can be used to build new software.
Non-language-specific lists are toward the end of
Assembly language and embedded CPUs
Mathematics and numerical analysis
More Than Just Libraries
Dan's software home page
The original version of this list debuted around 1999; links were last
updated March 2016, but this list is no longer actively maintained.
These days, there are better ways to find reusable software components.
