Stata Journal

Stata programs regularly accompany articles in the Stata Journal. These programs are typically most useful when you have access to the associated arcticle, but they often have online Stata help and can be installed regardless. See in particular Accessing Journal Software in the Stata Journal FAQ.

STB mirror sites

Prior to the Stata Journal, Stata Press published the Stata Technical Bulletin (STB). Associated with every issue of the STB was software adding new features to Stata. The best way to install these programs is directly from Stata; it can be done with a few mouse clicks. Also, the software is available over the web for access by browsers from either of the sites below:
