This document discusses alternative business models for academic journals as subscription revenue declines. It suggests journals can increase revenue through spin-off products like books, cascading rejected articles to related journals, obtaining subsidies from sponsors, and offering services to authors and readers. While open access works well for large science and medical journals, it is more challenging for smaller humanities and social science publications due to less funding and specialized topics. The document analyzes how open access journal finances vary based on submission volumes and acceptance rates.
