Self-publishers face prohibitively expensive ISBN acquisition costs that eat into already-thin profit margins

Self-published authors need ISBNs to distribute books through major retailers and libraries, but ISBN costs ($125+ per ISBN from Bowker in the US) represent a significant upfront expense for authors with limited budgets. Current solutions force authors to either pay premium prices, accept limited distribution, or use free ISBNs that lock them into specific print-on-demand platforms, creating a painful catch-22 between affordability and distribution freedom.
