Thin Line

Welcome to Thin Line! This collection preserves works originally hosted on Thin Line. Opened in 2001, Thin Line was originally a place for Severus Snape/Sirius Black fanfiction, that later expanded to accept works pairing Severus Snape with any member of the Black family in January 2006. Thin Line was a member of the Snape Slash Fleet, an association of archives centered around Severus Snape pairings. Though the archive closed in 2011, the content was backed up and saved by the moderator until its move to the Archive of Our Own.

Thin Line is OPEN to new works that pair Severus Snape with a male member of the Black family.

The import of this archive to the AO3 was approved by the OTW Open Doors Committee on 23 December 2020, and began in April 2021.

(Open, Moderated)

This collection contains works originally located at, which were imported to the Archive of Our Own through the Open Doors Project. Thin Line was taken off line in 2011, due to technical reasons. After a long delay, all files were found and the archive is being imported to the Archive of Our Own to avoid getting lost. You can learn more about the import in the import announcement.



If you still have access to the email you used to post your works to Thin Line, you should have received an email with the option to claim your works at the time they were imported. If you do not have access to that email account, or did not receive the notification, please contact the moderator at the contact email address listed above.

All unclaimed works are imported as restricted to logged-in AO3 users only, and will be made publicly viewable after a 30-day transition period. If you claimed your works before that period ended, you will need to change the restriction setting.
