Disclose your affiliation with the University of Miami Libraries on your Wikipedia user page before editing. (The user page can be found in the top right corner of any Wikipedia page and can be edited like a regular article).
If you edit articles about the University of Miami Libraries as an institution, other Wikipedia users may perceive a Conflict of Interest. Simple factual changes (e.g.: personnel updates or outdated statistics) may likely be made without raising eyebrows, but more substantive changes should be proposed with a critical eye towards a potential Conflict of Interest. Such articles should be edited using appropriate discussion pages, and encouraging feedback from other Wikipedia editors.
Additions to articles must be verifiable. This means that independent media or academic secondary sources should be cited whenever possible. Where published literature or web pages represent original scholarship, they may be cited, but they must go along with an additional verifiable source to back up this information.
When editing articles, always maintain the impartial voice. You are writing an encyclopedia, not speaking for the University of Miami Libraries.
