Update. "Accelerating Access to Research Results: New Implementation Date for the 2024 #NIH Public Access Policy"
https://www.nih.gov/about-nih/who-we-are/nih-director/statements/accelerating-access-research-results-new-implementation-date-2024-nih-public-access-policy
"I am excited to announce that one of my first actions as NIH Director is pushing the accelerator on policies to make NIH research findings freely and quickly available to the public. The 2024 Public Access Policy, originally slated to go into effect on December 31, 2025, will now be effective as of July 1, 2025."
PS: This announcement is from the Trump-appointed NIH director, #JayBhattacharya. It's another sign that Trump has not revoked or weakened the #OSTP #NelsonMemo, despite other attacks on research, including #takedowns of #OpenAccess texts and data. At the NIH, the largest funding agency, implementation of the Nelson memo is even speeding up.
EDIT. Another NIH reaffirmation of its NelsonMemo OA policy. From Lyric Jorgenson, NIH Ass Director for Science Policy, April 30, 2025: "We revised our Public Access Policy to eliminate the embargo period so that researchers, students, and members of the public have rapid access to these findings. NIH leadership believes strongly that transparency in all we do is critical and that we should not waste a moment in fulfilling our promise to the public."
