FIELD MANUAL / THE DOCUMENT THAT WON’T TELL YOU EVERYTHING
The Black Bar
How to read a redacted government file without making up what was hidden—and how to find what the surviving record can still prove.

Final Vestige Studios · Editorial/source check: November 7, 2026 · This guide explains research technique, not legal advice or a promise of access. State, local, judicial, congressional and foreign records may follow different regimes.
A thick black line invites a story. Someone has removed something; surely the missing words must be important. But the rectangle itself proves far less than it seems to. It does not tell you what was there, why each word was withheld, whether the withholding was lawful, or whether a separate version contains more. The useful clues are often printed around it: agency, case number, exemption notation, page count, release stamp, and the trail of decisions that brought this copy into your hands.
Tell an actual redaction apart from an unreleased page, a missing file, and an agency search that found no records.
Keep two releases aligned without calling every visible difference a revelation.
Identify the next sensible step: locate a public copy, narrow a request, consider an appeal, or use declassification review.
First, identify the kind of silence
Not every absence on a government records page is the same kind of absence. The distinctions determine which archive, question, or procedure to use next.
| What you see | What the record supports | What it does not establish |
|---|---|---|
| Blackout with an exemption label | The release presents content as withheld under a cited legal basis. | The hidden text, its motive, or whether the claim would survive independent review. |
| Page withheld in full | The agency reports a responsive page was not released in readable form. | That the page was blank, trivial, or necessarily classified. |
| Withdrawal notice in an archive folder | A described record has been removed or restricted from access under a particular archival process. | That the notice itself is the original record or that all restrictions arise under FOIA. |
| “No records” response | The agency reports its search did not locate responsive records. | That the event never happened, or that another agency/record series has no relevant records. |
| Page sequence gap / poor scan | This copy may be incomplete, misnumbered or inadequately captured. | That anyone intentionally withheld the missing page. |
Where an agency provides a determination letter, read it with the file. The letter may identify search scope, referral, consultation, release date, withholding provisions or appeal rights. Without it, you may be looking at a downstream repost whose history has already been stripped away. For federal FOIA procedures see FOIA.gov’s requester FAQ and NARA’s explanation of withdrawal notices.
What the marks beside the black bar mean
Federal FOIA has nine statutory exemptions. On many releases a mark such as (b)(6) points to an exemption in 5 U.S.C. § 552(b), not to a secret classification level. Agencies can format the labels differently. A label names a claimed basis for withholding; it does not reproduce the missing words.
| Code | Broad subject | Research caution |
|---|---|---|
| (b)(1) | Information properly classified under an executive order for national defense or foreign policy. | Do not mistake “classified” for a permanent status; declassification and access decisions are separate. |
| (b)(2) | Internal personnel rules and practices. | Not a general license to conceal embarrassing agency policy. |
| (b)(3) | Material withheld under another qualifying statute. | Identify which withholding statute the agency relies on. |
| (b)(4) | Trade secrets and privileged or confidential commercial/financial information. | Private-party information may appear inside government records. |
| (b)(5) | Protected inter- or intra-agency memoranda (including certain privileges). | Not every draft or discussion is automatically exempt. |
| (b)(6) | Personal privacy in personnel, medical and similar files. | A name withheld for privacy is not evidence of culpability. |
| (b)(7)(A–F) | Specified harms from disclosure of records compiled for law enforcement purposes: proceedings, fair trial, privacy, sources, techniques or safety. | The letter matters: (7)(C) privacy is not (7)(E) techniques. |
| (b)(8) | Information concerning examination, operation or condition reports for regulated financial institutions. | Institutional supervision context matters. |
| (b)(9) | Geological and geophysical information and data concerning wells. | Technical data may be withheld for reasons unrelated to national security. |
Practice: read the margins, not the missing words
Below is a completely invented teaching example. It copies no archival page, names no real agency, and does not depict any actual release. Look at what is visible before forming a theory about the black rectangles.
Memorandum of File Review
File series: DEMONSTRATION / RELEASE COPY
Review date: 00 / 00 / 0000 — a deliberately impossible placeholder.
The file contains a routing note and a contact entry. The contact name is shown as (b)(6) █████ in this fictional diagram.
A separate fictional passage is illustrated as (b)(1) █████. Nothing has been removed from a real original; these are teaching shapes.
SIMULATED / NOT A GOVERNMENT RECORD
What can you safely say? If a genuine agency copy displayed these labels, you could say that the released page identifies (b)(6) and (b)(1) as its stated withholding grounds. You could not say what the names were, what the classified passage said, or that the two protected items were connected. The invented page number and file label here demonstrate where you would capture identification data on a real item.
For an actual primary-source exercise, open the FBI’s Nikola Tesla file collection, select one FBI-hosted PDF, and record its visible file identifier, scan page, original document date (if shown), and any release markings you can verify. Do not assume the viewer’s PDF page number equals the source’s original folio number; document both when they differ. A file indexed under a historical person’s name is not a historical finding by itself.
The seven-pass reading method
- Find the controlling copy. Begin at the record-holding agency, FOIA.gov search, FBI Vault, or NARA. Keep the official landing page and the original PDF URL. A viral screenshot is a lead, not a source.
- Capture the envelope. Write down title, agency and component, collection or record group, file or case number, document date, release date (if known), download date, original page number, PDF page index, and every associated determination letter or withdrawal sheet.
- Describe, don’t decode. Log each visible redaction with page and displayed exemption code. If no code is visible, write “none visible.” Do not invent a reason to fill the gap.
- Look at the record’s neighbors. The pages before and after, enclosure lists, routing slips, finding aids, cited memo numbers, and chronological correspondence often reveal the document’s function without disclosing protected content.
- Compare versions conservatively. Align by same document ID, date, page and paragraph—not merely similar topics. Record release A and release B separately. Different scans, page order, reprocessing or PDF cropping may explain differences.
- Separate three voices. In your notes mark each statement Observed (visible), Corroborated (supported elsewhere), or Hypothesis (plausible but unproved). A blank is not permission to write a plot.
- Choose the correct route. Search another publicly available release first. If a federal agency’s response is adverse, read the appeal instructions; for classified records consider whether MDR rather than a new FOIA request is appropriate. Preserve all response letters and dates.
Request, appeal, or declassification review?
| Situation | First sensible route | Important constraint |
|---|---|---|
| You want federal agency records not publicly posted | Send a written FOIA request to the appropriate agency/component, reasonably describing the existing records and preferred format. | FOIA does not require an agency to create a new record or answer an open-ended research question. Fees and special access rules may apply. |
| You received a partial denial or “no records” determination | Read that agency’s determination letter and consider an administrative appeal; contact its FOIA Public Liaison or OGIS for help. | Federal law requires at least 90 days to file an administrative appeal after an adverse determination. Follow the actual letter for method and exact deadline. |
| You can identify specific classified federal information | Consider Mandatory Declassification Review (MDR) under EO 13526, where eligible. | Conditions, agency routing and exclusions apply; the same requester cannot pursue FOIA and MDR concurrently for the same information. |
| An archival withdrawal sheet stands where a record should be | Record the withdrawal identifier; ask the relevant NARA unit or originating agency which review process applies. | A withdrawn archival item may have restrictions other than national-security classification. |
Appeal is not the same as mediation. DOJ guidance explains that adverse FOIA determinations may be appealed, including withholding and search issues. OGIS provides FOIA dispute-resolution assistance. Its involvement does not automatically stop an appeal deadline. The DOJ appeals guide explains the statutory framework; read the response letter from the agency handling your records for case-specific instructions.
A usable request sentence
“Under the Freedom of Information Act, I request copies of existing [document type] created or received by [office] between [dates] concerning [specific project or file number]. If available, please provide electronic copies with legible original page numbering and associated enclosures. I am seeking records, not an explanation prepared in response to this request. Please advise of any applicable fees or procedures before incurring charges above [amount].”
This is research drafting help, not a legally guaranteed template. Use the agency’s current submission instructions and consider privacy, sensitive personal information, and its regulations. See FOIA.gov’s FAQ.

What a responsible citation should preserve
A defensible reference says who holds it, which copy you used, where the reader can inspect it, and what that copy cannot establish. Cite an original document date separately from a release date and a web-access date. Keep document ID, record-group or series, source URL, page identifiers, and any later-release distinction. If you cropped a facsimile, call it a crop; if a transcription was manually made, label it a transcription and retain the scan.
The National Archives’ rights guidance draws a crucial boundary: many works created by federal employees as part of official duties are public domain in the United States, but a record held by NARA may incorporate privately copyrighted or otherwise restricted material. This page links to actual files rather than republishing their scans. The mock redaction is our own teaching illustration; it is not archival evidence.
Ethics: do not try to reverse a proper redaction, expose private individuals, or treat every withheld name as a suspect. A released file can contain error, allegation, speculation, and one-sided reporting; provenance tells you where a claim came from, not whether it is true.
