They Burned The Files And Kept The Receipts
The programme's substantive records were destroyed in 1973. Its expense vouchers survived, in a different building, under a different retention schedule. Eleven cost centres appear only there. A voucher records a payment, not a purpose.
A months-long reporting project. Documents cited below are held in The Vault and available to readers.
COLLEGE PARK, Md. — The substantive files were destroyed in January 1973 on the director's order. That is well documented, was admitted at length in Senate testimony, and is not news.
The expense vouchers were not destroyed, because the expense vouchers were in a different building, under a different retention schedule, held by people who had never heard of the programme and were following a rule about financial records.
They are public. Anybody may go and read them. Our correspondent has now read 62 of the 91 boxes.
Why they survived
Dr. Ottavia Brennan-Kealoha, who has worked this series since 2009, explains it in one sentence: destruction orders travel down programme lines, and accounting is not a programme line.
The two retention schedules are both published. One governs operational files and permits destruction on the originating office's authority. The other governs financial records and requires retention for a fixed term followed by transfer to the national archive. Nobody reconciled them, because reconciling them was nobody's job.
What a voucher is
A payment, a date, a payee, a cost centre, and a countersignature. That is all.
It does not say what the money bought. It does not say what the subproject was for. Where the payee is a university, it names the university and not the researcher; where the payee is an individual, it names the individual and gives no title.
This newspaper is going to be extremely dull about that limitation because the entire value of this story depends on it.
The eleven
Sixty-two boxes yielded 3,908 vouchers carrying subproject cost-centre numbers. Most correspond to subprojects already described in the published literature.
Eleven do not appear in any published index, congressional annex, or secondary work our correspondent or Dr. Brennan-Kealoha has been able to find, and both of them have been looking since March.
| Cost centre | Vouchers | First | Last | Payee type |
|---|---|---|---|---|
| 14-B-062 | 41 | 1955 | 1959 | University |
| 14-B-071 | 19 | 1956 | 1958 | Individual |

What this story is not
It is not a revelation of eleven hidden experiments. We do not know that any of them was an experiment.
A cost centre with four vouchers to a commercial supplier in 1959 might be a research programme. It might equally be a shelving order. The record cannot distinguish and neither can we.
What it is: eleven numbers that the published record does not account for, in a public series, that anybody may go and check, and that this newspaper is publishing so that somebody with more time and better Sixties chemistry than either of us can do the next part.
Dr. Brennan-Kealoha asked us to end on her sentence rather than ours, and it is a better ending than we had.
"Everybody wants the file that was burned," she said. "Nobody wants the receipts. The receipts are in a box in Maryland and the reading room is open on Tuesdays."

Sources & Method
Nine visits to a public reading room over fourteen months, reading 62 of 91 boxes of expense vouchers page by page and recording every cost-centre number. Then the two retention schedules that explain why one set of records was destroyed and the other was not. Everything in this story is a public record that any member of the public may go and read, and the story says so in the second paragraph rather than implying otherwise.

- Two retired agency records officers, Named in our notes; both spoke on the record. Telephone May 2026 Both explained the two retention schedules without being told why we were asking.

What we could not confirm
- What any of the eleven subprojects did. A voucher records a payment, a date, a cost centre and a payee. It does not record a purpose and we are not going to infer one.
- Whether the eleven are a complete list. They are the eleven that appear in the series we have read, which is 62 of 91 boxes.
- Whether the substantive files for these eleven were among those destroyed in 1973 or never existed in that form.
