There is a known issue with some of our PDF files being labeled as ‘corrupted’. These files are fine, but some newly implemented security rules are regarding PDF files with a comma in the title (and some special characters) as a security risk. Unfortunately, that includes all of our Journal issues.
UPDATE: As of June 18th, 2026, the issue with loading our PDF files for the NCGS Journal (and various other PDF files) has been resolved. If you still see this issue, please try refreshing your browser tab. If it persists, please contact we*******@*********gy.org to report it.
Thank you for your patience!
