manifestata is a free add-on for the commerical statistical software Stata. It provides access to coded election programmes from the Manifesto Corpus and to the Manifesto Project's Main Dataset.

preface: manifestata is currently (as of 2021-02-12) somewhat unmaintained. This means that there are no immediate plans to a) fix the currently existing bug regarding accessing the corpus nor b) possibly existing problems on non-windows machines. In case you are doing text analysis based on the Manifesto Corpus we would like to refer you to our R-package manifestoR (also as in R there is a much larger universe of packages that can help you with text analysis). If you have a desire for fixes or think we should reevaluate our decision please contact us.
