After reading about [editing a URL after publishing](https://talk.observablehq.com/t/way-to-edit-the-url-after-publishing/190/9), I went to un-publish a notebook where I made a typo in the title [which carried into the slug](https://observablehq.com/@aaronkyle/cao-dyanamic-case-naming) (a characteristic mistake for me). To my surprise, there was no option to un-publish! After playing around, I’ve determine that it’s not the fact that I forked the notebook that prevents it from being unpublished. Might it instead be due to the fact that this particular notebook pre-dates the un-publish option? ---

You can only unpublish within twenty-four hours of first publishing. You can send us a support request if you’d like to change the URL, or you can fork your notebook and publish the fork under the corrected URL. ---

Thanks Mike! I won’t trouble your team with a support request, as it’s not so important for me to keep the date. Interesting that there’s a time limit to unpublishing! ---

As a bit of a follow-up? Is there a time limit before a URL become available again after trashing a notebook? That is: In my test, I trashed the notebook with the correct slug. Now I when I go to publish the new notebook, I am getting a trailing number, e.g., [http://correct-slug/2](http://correct-slug/2) ---

Once a slug is used, it is never available to other notebooks, even if you trash the notebook that used the slug. ---

> [@mbostock](#): > > Once a slug is used, it is never available to other notebooks Thanks for the clarification. I assumed the behavior would be the same as for collections, but it makes sense to blacklist used notebook slugs.
