This is tutorial on how to annotate PDFs in Adobe Acrobat geared primarily for scholars in the humanities. The chances of actually making use of our notes, as I’ve argued earlier, hinges heavily upon their immanent visibility – being able to see which passages have been annotated within a text without having to cross-reference separate documents. Shifting to digital text not only enhances their searchability and modularity, it also allows us to layer annotation and citation within the text itself.
