With kavod (honor) to “all whose hearts were stirred to share” (kol asher nasa libam, cf. Exodus 36:2-3), this is a searchable index of all liturgists, translators, transcribers, etc. whose work on Jewish prayer, on prayer books, and on public readings is being shared through the Open Siddur Project. After ten years, the total number of project contributors is nearly 800. A little over half have shared their work either directly with the project with an Open Content license, or indirectly by contributing their work into the Public Domain as a contributor to a government publication. Nearly fifty are institutional copyright stewards (operating or defunct for-profit and non-profit entities). The remaining contributors have had their works transcribed from material that has passed into the Public Domain after their deaths. Some transcribed works shared through the Open Siddur project remain unattributed due to unknown authorship. If you find an uncredited or improperly attributed work, please contact us.

To join this community of contributors, please share your work. Making prayers and related religious works available for creative reuse and republication through Open Content licenses is crucial for keeping Jewish culture cross-pollinating, vital, and relevant under the current climate of denominationally identified silos and proprietary-by-default copyright strictures. Prospective contributors should read our Mission Statement, Terms of Use, and Copyleft Policy. The Open Siddur is a non-prescriptive, non-denominational project and invites participation without prejudice towards ethnic heritage, skin color, nationality, belief or non-belief, sex, gender, sexuality or any other consideration.
