Good reading material soon gets irrepressibly relevant. Every conversation becomes enlightened by referring to it. Every teaching can incorporate it as an amusing digression.
Take Augustine's **Confessions**. The first book belongs to philosophy of language; the second book can be used for philosophical anthropology; the third one can be of interest for the historian of theater. And to worsen matters, each quotation can serve many projects.
This relationship between projects and quotations has consequences. Bibliographical entries should not contain annotations specific to one project. Citations shall use centralized references. Tools like wikis may improve bibliographical work, as they maintain many-to-one mappings.
Separating reading notes from bibliographical information will help us cite as we like.
