The source's quotation collection moves between Bach's Coffee Cantata, remarks about coffee across national borders and anecdotes associated with travel or exploration. Those references show how widely coffee appears in cultural writing, but a collection is not the same thing as a documented historical timeline.
A lyric, a joke and a reported spoken remark need different kinds of context. Who wrote the work, when it appeared and whether a later source changed the wording all affect how an attribution should be understood. A humorous complaint about a country's coffee is especially easy to detach from its original setting and mistake for a serious assessment of coffee quality.
For a café reading list or a cultural article, choose a few references you can trace rather than repeating a long list of names. Discuss what the reference contributes: affection for a daily ritual, a contrast between places, or the social life of coffee drinking. The subject becomes more interesting when the original context remains visible, and no borrowed line has to stand in for evidence it never intended to provide.

A good question can make a better brew.
