Mission and programs · 2024

Mission

TO ADVANCE RESEARCH OF THE HERCULANEUM PAPYRI AND ONGOING EFFORTS TO DECIPHER THEM.

  • IN 2024, VESUVIUS CHALLENGE SUCCESSFULLY RESULTED IN THE NONINVASIVE RECOVERY OF MULTIPLE PASSAGES OF TEXT FROM AN INTACT HERCULANEUM SCROLL. THE HERCULANEUM SCROLLS REPRESENT THE ONLY LIBRARY FROM ANTIQUITY TO SURVIVE IN-SITU, AND IF READ WILL SIGNIFICANTLY INCREASE THE WORLD'S ACCESS TO ANCIENT TEXTS. SINCE THEIR DISCOVERY IN THE MID EIGHTEENTH CENTURY, THE SCROLLS HAVE BEEN THE SUBJECT OF 250+ YEARS OF UNROLLING ATTEMPTS. ALL HAVE BEEN OVERWHELMINGLY DESTRUCTIVE OR UNSUCCESSFUL, UNTIL NOW. WE NOW HAVE METHODS CAPABLE OF RECOVERING THE CONTENTS OF THE SCROLLS WITHOUT DAMAGING THEM, A PATHWAY THAT WILL ENABLE THE COMPLETE RECOVERY OF THIS LIBRARY AS OUR WORK CONTINUES.

Compensation is as filed in Part VII: reportable pay from this organization and from related organizations, other compensation, and hours per week. The total, marked calculated, is our sum of the three dollar columns, with a blank column counted as $0; the form itself has no total. On a Form 990-EZ the columns are Part IV's instead, and on a Form 990-PF Part VIII's — compensation, contributions to benefit plans, and expense account — and the total sums those. Earlier years are each on their own filing page.

Other IRS files

Auto-Revocation List

Not listed. The IRS publishes this list for organizations whose exemption was automatically revoked for failing to file for three consecutive years.

Publication 78

Listed as of 13 October 2026, under deductibility PC.

These are two separate IRS files on two separate schedules, shown as published and not reconciled with each other. Neither is a statement about whether a contribution is deductible today: 19,245 organizations appear in Publication 78 while the IRS's own revocation file lists them as currently revoked, more than half of those revoked before 2019. Absence from Publication 78 is evidence of nothing, and presence is not evidence either. Verify current status with the IRS before relying on it.
