külgviited
Külgviited, often translated as side notes or marginalia, are annotations or commentary that appear in the margins of a text. Historically, these were handwritten by readers, scholars, or scribes to offer explanations, critiques, cross-references, or additional information related to the main body of the work. They served as a way for individuals to interact with the text, personalize their understanding, and engage in a dialogue with the author or previous readers. The practice of adding külgviited was particularly prevalent in manuscript cultures where texts were unique and often annotated by multiple individuals over time, creating layers of commentary.
In printed books, külgviited could be incorporated by the publisher or author as formal footnotes or endnotes,
