Footnotes

Extracted from the Wikipedia article Note (typography).
Footnotes are informational notes located at the foot of the thematically relevant page, whilst endnotes are informational notes published at the end of a chapter, the end of a volume, or the conclusion of a multi-volume book. Unlike footnotes, which require manipulating the page design (text-block and page layouts) to accommodate the additional text, endnotes are advantageous to editorial production because the textual inclusion does not alter the design of the publication. However, graphic designers of contemporary editions of the Bible often place the notes in a narrow column in the page centre, between two columns of biblical text.
