Generally, no (see our Terms of Service). Our goal is to preserve and provide access to work submitted to CORE, and we strongly discourage the withdrawal of items from it. CORE is designed to provide its users with a permanent and accessible record of their scholarship, and assures continued access to that scholarship through its robust archiving features and the minting of DOIs. These DOIs are then indexed by a number of external services, and by minting them, we are assuring a working link to the content to which they refer. If you have published a version of the work elsewhere and wish to point to that version in the Notes field of your CORE deposit, please let us know.
In exceptional cases, we may remove an item at the author’s request. However, although the item itself will be removed, the record of its existence will persist in CORE, along with text explaining why it is not longer available.
