If you've made a mistake or want to update a publication, that you've already published with Issuu, we've made it easy for you to submit a new version of the document.
Go to My Library and select the publication you want to update.
Select ‘More’ (or right-click) and choose ‘Update publication’.
‘Browse’ to the new version and hit ‘Upload file’.

That’s it. The publication will keep all your comments, stats, and bookmarks. It’ll even have the same publication link as before.
Note: To prevent misuse of this feature we have to change the updated publication’s ID number. This means that anyone who has embedded the publication must re-embed it.
