RLetters is an application designed to let users perform complex searches as well as digital-humanities and text-mining analysis tasks on a corpus of journal articles.
RLetters allows users to save the results of a given search as a “dataset.” This produces a saved record that users can return to later in order to perform text analysis tasks.
While text analysis tasks are a current area of active development in RLetters, currently the following are available:
The Solr backend on which RLetters is based allows for a number of complicated searching operations:
RLetters features a JSON API to return search results to other services around the internet. We also provide support for the following web and library standards:
And you can export bibliographic data in the following standard formats:
RLetters doesn't leave your developers out in the cold, either. We've got speedy deployments with Ansible and Capistrano, exception monitoring with Sentry, and our code has a thorough test suite and adheres to a probably unnecessary level of linting and style-guide fanaticism.

We also have received the help of a great community of translators at Transifex. Thanks especially to Alejandro León Aznar.
Also, several features of RLetters wouldn't be possible without the excellent work of other Ruby programmers. Thanks in particular to those behind Ansible, RSolr and RSolr::Ext, and bibtex-ruby. The stop lists found in
