Schonfeld writes: “The OSTP Nelson Memo’s Public Access policy guidance [requiring taxpayer-supported research to be available open access] has caused quite a stir in scholarly communication circles. Many publishers are understandably concerned about how an accelerated US transition to open access will impact their revenue and bottom line. Some library leaders are confident that they have the right frameworks already in place for their institutions. For others, even though the library community lobbied heavily for this very outcome through SPARC, there appears to be substantial uncertainty about how academia will adapt. How will academia handle the zero embargo?”
