The Materials Project has recently undergone a major change in its website architecture. More information on this can be seen in the release announcement.

It is recommended that the URL https://materialsproject.org is used as the primary location of the Materials Project websitehowever a specific website version can be visited via the following links:

• https://next-gen.materialsproject.org will always take visitors to the latest Materials Project website with the newest database version available.

• https://legacy.materialsproject.org will take visitors to a frozen snapshot of the older Materials Project website. This is powered by an older version of the database with known issues. The legacy website is being left online for some time as we fully transition to the next-gen websiteand to allow users time to make any adjustments as necessary for features that may only be available on the legacy websitehowever the legacy website will be taken offline in due course.

Documentation

The Materials Project documentation has gone through several iterationspowered previously by MediaWiki and MkDocs software. The current version is powered by GitBook. This switch was made to allow more easy and rapid changes to the documentationin the hopes of ensuring documentation is maintained at a consistenthigh quality.

The current documentation is also available via GitHub at https://github.com/materialsproject/public-docs. Edits and improvements from external users are very welcomeplease submit a "pull request" with any suggest change or use the "Edit in GitHub" button on the relevant page.

The previous MkDocs documentation is still available for the historical recordand the older MediaWiki documentation are currently offline but available on request. Howeverthe current version of the documentation should contain all necessary information including historical information. An effort has been made to ensure URLs remain the same during the transition from the previous MkDocs-powered documentation to the new GitBook-powered documentation.
