Response to letters to the editor / Comments to the editor
Are “response to letters to the editor”, “comments to the editor”, etc. included in ZORA?
Yes, if they were published in one of the publication types in the guide, typically as a journal article or book section. They are usually considered "further contribution", not "original article". If the submitter indicates "non-refereed", even if the journal as such is considered refereed, the ZORA editors leave this indication (non-refereed). Reason: such publications are in fact often non-refereed, even if they appear in a refereed journal.
