After a college professor writes an academic journal article, it usually has a long but vivid transit to publication. The professor sends it to a journal, where it endures rounds of reviews and edits by other academics. Eventually, it's scheduled for publication, and it waits, not yet born. Then its big day comes--it's published!--and formatted, printed, bound and mailed to subscribing institutions, and uploaded to a journal's servers. Perhaps the professor's home college or university receives the print copy, perhaps they've purchased server access, but, regardless, they pay twice: Once for the research, and once for the product of that research.
