There's a couple of ways you can edit the titles for your coverage.

When you first upload an offline clip, we'll ask you to select the outlet/publication first (select from the drop down if you've added this outlet before, or click on the + to add a new one).

Then, you can edit the title before uploading the clip:

If you wanted to edit a clip already in your book, click on the Edit option and you can change all the details.

For Online Coverage:

Just follow the same step above - go to the clip in your book and hit the edit option in the top right corner to change the title, add a custom URL and more.
