This is context in which I would use.
I have a long bibliography of references in a Microsoft Word. Here are three examples:
1. Kear, J., Editor (2005). Ducks, Geese and Swans. Volume 1: General chapters, and Species accounts (Anhima to Salvadorina). Oxford University Press, Oxford, UK.
2. Brazil, M. (2009). Field Guide to the Birds of East Asia: Eastern China, Taiwan, Korea, Japan and Eastern Russia. Christopher Helm, London, UK.
3. Øien, I. J., P. Tolvanen, T. Aarvak, and J. Markkola (1999). Occurrence and identification of Lesser While-fronted Goose. Alula 5(1):18–23.
These references are also saved as PDFs on my computer. Instead of having to open Alfred and and type 'Field Guide to the Birds of East Asia to find the PDF, I want to select "Field Guide to the Birds of East Asia" in the bibliography of the Microsoft Word document and use the selected text to open the PDF.
