Data Release Publications

On this page

With each data release, the Sloan Digital Sky Survey collaboration has published a Data Release paper, which describes the data, the data acquisition process, and other details of the project.

The most current public data release of the SDSS-V is Data Release 18 (DR18), which was released in January 2023. Details of DR18 are described in the Data Release 18 paper (Almeida et al. 2023).

This page gives links to the published paper for each data release, which serves as the official academic record for that release. When publishing research with data from one or more of our data releases, please reference the appropriate paper from the list below, along with any technical publications necessary for the reader to understand how the data were collected. Please see our guide on how to cite SDSS. Thank you, and we hope you find our data useful!
