The BitCurator group on GitHub is the primary store for all source code and development documentation developed as part of the Andrew W. Mellon Foundation funded BitCurator NLP (2016-2018), BitCurator Access (2014-2016), and BitCurator (2011-2014) projects.

Additional information, user documentation, and community contributions to the BitCurator Environment can be found on the BitCurator Environment wiki. Ongoing support for the BitCurator Environment is provided by members of the BitCurator Consortium.


BitCurator Environment

The BitCurator Environment (Live CD / Installation CD) is comprised of several repositories (two of which, -adduser and -metadata, are optional).

Users looking for the latest release should visit to download the ISO or preconfigured virtual machine. Alternatively, check out the README at to see how to build BitCurator in a stock Ubuntu install. Developers should first consult the README in bitcurator-distro for information regarding contributions (test builds, pull requests, and other modifictions). Note that some older repositories are deprecated.

BitCurator Access Webtools

The BitCurator Access Webtools project is comprised of a single repository. The README provides instructions for both end users and developers to clone and build from source.

BitCurator Access Redaction Tools

The BitCurator Access Redaction tools project is comprised of two repositories. The READMEs provide instructions for both end users and developers to clone and build from source.

BitCurator NLP Tools

The BitCurator NLP project includes several repositories. The topic model generation environment (bitcurator-nlp-gentm) enables automatic extraction of text from heterogeneous document collections within disk images to generate user-browsable topic models within a web browser. The disk browsing environment (bitcurator-access-webtools) provides full-text browsing of documents contained within disk images, along with (in progress) analysis of entities identified within those documents. Various command-line tools are provided in another repository (bitcurator-nlp-entspan).
