Once deposited, content should not normally be modified. If removal is necessary, that process will follow the Withdrawal Policy (see below). If the description of the content (its metadata) is incorrect, the depositor must send an explanation of the error and its correction to the eCommons Administrator. Reasonable corrections to metadata will be made by eCommons staff.
Adding a new version or replacement of content is allowable according to the following policies.
Adding a new version
If the depositor wishes to update a work, providing a new version of an existing eCommons item, he/she must contact the eCommons Administrator with an explanation. Standard practice is for eCommons to maintain access to previous versions, with all versions visible on the landing page, with the reason for each subsequent version. The newest version is listed first, and the original handle always resolves to the newest version. Handles for older version are generated by appending a number to the original handle, so it remains possible to refer to a specific older version when a newer one exists.
Complete replacement of a file requires justification from the requestor. The requestor must note in their request the specific changes that have been made, in order to allow eCommons staff to assess the request.
Examples of reasonable requests for replacement include correcting errors, or marking a version of an item as deprecated or superseded. Superseded content may be indicated by adding a watermark or cover page to the replacement item (for example), stating that the content has been superseded. Such content modification is the responsibility of the requestor. When a replacement is made, a note will be added to the content description ("Content replaced at author's request on [date] for [reason]").
There are some cases in which a replacement cannot be made, such as requests to replace an official record such as a thesis or dissertation that has been formally approved.
eCommons is intended to provide persistent access to deposited material. Under certain circumstances, however, it may be necessary to remove material from eCommons.
A request for removal should be directed to the eCommons Administrator and include the reasons for withdrawal. eCommons staff may contact the requestor for additional information.
Since the goal of eCommons is persistent long-term access to content, original item records are retained for all withdrawn content. These records, including all original metadata, will be displayed to users. These records will contain one of the following statements:
Item removed from eCommons on [date] at the request of the author.
Item removed from eCommons on [date] by legal order.
Item removed from eCommons on [date] due to a violation of eCommons policy.
Item removed from eCommons on [date] at Cornell University Library's discretion.
