I'm seeing the following abbreviation in several book/manuscript citations, particularly in religious works, but I have no idea what the abbreviation means. From the context of where I'm finding it, I'm assuming it is a Latin abbreviation. Does anyone know what it stands for?
tom. i.
Used (for example) in the following citation: 1690, tom. i. col. 1006. 25. Ejusdem Sermo * de nativitate Beate Marie.” fol. 74. b. Impress. ibid. tom. i. col. 1012. 26. Ejusdem Sermo * ad abbates et fratres.” fol. 79. b. Impress. ibid. tom. i. col. 1155. 27. Ejusdem Sermones duo * de angelis.” fol.
