Related to this question on cross-checking APA citations and references, I often have an existing list of APA formatted references. This might come from a document from a collaborator or it might just be a published article.
I often want to take this list of APA references (e.g., one reference per line) and import them into my bibliographic software in such a way that the reference manager is able to discern what aspects of the reference correspond to author, year, title, journal, issue, pages, etc. I'm often working with Endnote to do this, but I imagine that once you get the data into any reference manager (e.g., Mendeley, Zotero, etc.), it would be relatively easy to export and import into a preferred reference manager.
I'd also be happy with a system that was pretty good but not perfect. In psychology at least, most references are journal articles, book chapters, and books. So a system that imported these and flagged the rest would still be useful.
Question
How can an existing list of APA references be automatically imported into a reference manager?
