=== - The public monographs and translation PDFs carefully describe the cryptanalytic method (Soviet messages were code groups superenciphered by adding random digits from one-time pads; depth discovery; the isolation of duplicate pad pages) and they publish translations of many messages along with editorial notes. They note when groups are unrecoverable and provide message serial numbers and context. nsa.gov<ref>{{cite web|title=nsa.gov|url=https://www.nsa.gov/Portals/70/documents/news-features/declassified-documents/crypto-almanac-50th/VENONA_An_Overview.pdf|publisher=nsa.gov|access-date=2025-11-30}}</ref> ===
* The public translation packets and compilations (for example the New York 1944 and New York 1945 collections) typically present the final transcription and translated plaintext plus editorial notes. Where the released PDFs show cipher material, it is commonly the recovered plaintext with bracketed indications such as “[2 groups unrecovered]” or “[xx groups unrecoverable]”. In many public releases the original raw working worksheets used by the Arlington Hall analysts — the analysts’ internal pages showing the ciphertext 5-digit groups, the matching pad additive fragments in depth, and hand arithmetic transcribed step-by-step — are not included in the public PDF packages I reviewed.

* In short: public PDFs provide the narrative, the list of message numbers, and the final translations; they document the existence of depths and show many decrypted messages. They do not, as a rule, include the internal handwritten worksheets that show the precise original digit-by-digit subtraction steps and the original pad page fragments used at the analyst’s desk. If you have an exact internal worksheet image in mind, it is likely part of archival material not present in the mainstream public monograph/translation PDFs. The NSA FOIA archive may hold additional internal worksheets or case files; those must be requested or located in specific FOIA documents. nsa.gov<ref>{{cite web|title=nsa.gov|url=https://www.nsa.gov/Portals/70/documents/news-features/declassified-documents/crypto-almanac-50th/VENONA_An_Overview.pdf|publisher=nsa.gov|access-date=2025-11-30}}</ref>
