Documentation before action is the principle that a collectible should be identified, examined and recorded before it is cleaned, repaired, dismantled, stabilised, reframed, repackaged or otherwise altered. It is one of preventive conservation's most consequential disciplines because the first intervention may erase evidence that cannot later be reconstructed.
Dust may show how an object was stored. A stain may reveal an old attachment. A crease may document use. A clumsy repair may still belong to the object's history. Even moving loose fragments without recording their positions can destroy information. Documentation is therefore not an administrative afterthought: it is part of preserving the object.
The central rule
Record the object as it exists before attempting to improve it.
The more irreversible, invasive, valuable or uncertain the proposed action, the more complete the preliminary record should be. This remains true when the action appears minor: brushing dust, tightening a screw, replacing a sleeve, unfolding paper, removing a price label or testing a solvent.
Evidence
Wear, residues, labels, repairs, fasteners, stains, surface finishes, packaging and component arrangement may all carry information about manufacture, ownership, use and storage. Intervention does not begin with a blank object; it begins with an existing body of evidence.
Meaning
A dated written and photographic baseline makes later comparison possible. It can show whether a crack extended, a stain spread, a plastic yellowed, corrosion became active or an adhesive continued to migrate.
Collector risk
Cleaning, polishing, unfolding, opening, dismantling, replacing packaging or moving fragments may improve appearance or reduce risk, yet also remove evidence that cannot be recreated. The first duty is to understand what may be lost by acting.
Chapter I
A pre-action record does more than show what an object looked like. It preserves evidence, restrains misdiagnosis, supports proportional decisions and creates accountability for what follows.
A moved object no longer proves where it sat. A cleaned surface no longer shows the original deposit pattern. A dried item no longer shows the first distribution of moisture. Removed packaging may no longer explain why staining, abrasion or distortion appeared where it did. Action may be justified and beneficial, but it still changes what can be known.
A mark may be a manufacturing irregularity, deliberate finish, production residue, original adhesive, retailer's price mark, casting seam, registration fault, historical repair or evidence of use. Apparent corrosion may be intentional patina. Apparent dirt may carry historical meaning. Documentation creates the pause in which observation can be separated from assumption.
One observation describes the present. Repeated comparable observations establish whether change is occurring. Dated views and measurements can reveal extending cracks, spreading stains, increasing tackiness, lifting paint, deforming blisters, crumbling foam or adhesive migration that memory alone would miss.
The most useful preservation record is wider than a close-up of damage. It links condition to the physical and environmental relationships that may explain it.
Identity, materials, construction, overall condition, exact damage locations, previous repairs, marks, inscriptions, loose parts and signs of possible active change.
Box, sleeve, frame, mount, album page, blister, foam insert, backing board, ties, labels, contact points, pressure, abrasion, staining and the original position of components.
Shelf, cabinet, room, light exposure, recent transport, leak, temperature or humidity event, neighbouring objects, pest evidence and any change in storage or display history.
A comic is slightly cockled, the backing board has a faint tide mark and the closed box smells musty. The instinct is to remove the comic, discard the board and wipe the shelf. The disciplined collector first photographs the box in place, the object's orientation, neighbouring items, the board, staining pattern and storage area. That brief pause can establish whether the problem is local, environmental, recent or recurring - and preserve evidence for insurance, grading or specialist advice.
Chapter II
A strong condition record distinguishes what was observed from what the collector believes it means. It also shows how certain that interpretation is and what consequence the feature may have.
Observed feature
Describe colour, texture, location, dimensions, movement, odour, tackiness, powdering, distortion or looseness before naming a cause.
Activity
Fresh fragments, accumulating powder, spreading stains or repeated adhesive transfer may indicate activity. When evidence is insufficient, record that activity has not yet been established and monitor.
Consequence
Separate cosmetic alteration from structural instability, component loss, transfer to adjacent materials, health hazards or loss of historical and market evidence.
Confidence
Use terms such as possible, suspected, appears consistent with or requires specialist confirmation. Material and deposit misidentification is a common route to damaging treatment.
Overclaiming
“The plastic is suffering from irreversible polymer oxidation.”
This presents a material diagnosis and mechanism as established fact, even if neither has been confirmed.
Evidence-led
“The clear plastic has yellowed overall and has fine cracks at the folded corners.”
Interpretation can then be added separately: the pattern may be consistent with ageing and light exposure, but material identity and cause remain unconfirmed.
Chapter III
The record must identify the object, define the limitations of the examination and locate significant features precisely enough that another person can understand and revisit them.
Chapter IV
Different actions erase different kinds of evidence. The right preliminary record is therefore shaped by the intervention being considered.
Before you act
Collector risk
Cleaning is irreversible because material is removed. The test is not simply whether dirt comes away, but whether original surface, finish, colour or historical residue comes with it.
Boundary
Stop where paint, printing, gilding, powdery surfaces, uncertain coatings or significant inscriptions could be disturbed.
Before you act
Collector risk
Opening may permanently change the object's collectible category, authenticity evidence and financial value. It is not merely a packaging decision.
Boundary
Do not open solely to improve documentation when sealed status is itself significant.
Before you act
Collector risk
Reassembly is rarely as obvious as it appears before work begins. Dismantling can reveal information, but it can also destroy original relationships or introduce mechanical damage.
Boundary
Complex mechanisms, brittle plastics, concealed wiring and tensioned parts belong beyond the casual collector threshold.
Before you act
Collector risk
A fold may be intentional, and humidification, heat or pressure may alter inks, adhesives, board coatings or fibre structure. Better support may be safer than forcing a visual correction.
Before you act
Collector risk
Polishing can remove plating, original finish, manufacturing evidence and accepted patina. A polished surface cannot be returned to its previous state.
Before you act
Collector risk
Brushing or moving a suspect object can distribute spores and erase the pattern that helps diagnose the source. Isolation and environmental control may be the first response, not cleaning.
Boundary
Active or extensive mould, vulnerable media and uncertain health risks require specialist advice.
Before you act
Collector risk
The restorer's record does not replace the owner's baseline. Independent documentation protects both parties and prevents later disagreement about starting condition, scope and change.
Chapter V
Documentation is most powerful when it records not only what exists, but why action is proposed, which alternatives were considered and where authority ends.
State what is observed, where it is, and what appears to be at risk. Do not let the desired treatment define the diagnosis.
Reduce active risk, prevent component loss, improve support, isolate incompatible materials, enable safe transport or simply establish whether change is continuing.
No action, monitoring, improved storage, environmental correction, temporary support, separation, restricted handling or specialist review may solve the preservation problem without altering the object.
Balance the risks of staining, abrasion, swelling, colour loss, residue and evidence loss against the risks of corrosion, mould, distortion, migration or fragment loss continuing.
Record who can approve the action, what must not be touched, what test is permitted and which result requires the work to stop.
Risks of action
Staining, abrasion, colour loss, swelling, deformation, residue, gloss change, adhesive penetration, damage during disassembly, market-value change and loss of historical evidence.
Risks of inaction
Continued corrosion, loose-flake loss, mould spread, adhesive migration, distortion, pest activity, component loss and transfer of degraded material to neighbouring objects.
Proportionate does not mean optional. It means scaling the record to the object's significance, complexity, fragility, uncertainty and the irreversibility of the proposed work.
Basic
Identity, date, overall photographs, brief condition note, reason for action and the intended change. Appropriate for routine rehousing where materials and risks are understood.
Detailed
Full identification, materials and construction, accessible views, measurements, annotated damage, packaging and environmental context, old repairs and monitoring needs.
Treatment-level
Detailed examination, purpose, alternatives, risks, proposed materials, test areas, authorisation, criteria for stopping and a plan for recording work as it happens.
Specialist
Microscopy, ultraviolet or infrared imaging, radiography, material identification, moisture measurement, sampling or scientific analysis where justified and carried out by appropriate expertise.
Chapter VI
The aim of preliminary documentation is not to make every treatment possible. It is to reveal when the collector should not proceed.
Preliminary documentation does not grant permission to proceed. Its most important result may be the recognition that the safest action is to stop, isolate, support or seek specialist advice.
Flaking or powdering paint, lifting photographic emulsion, friable printing, severe brittleness or mobile corrosion products.
Sticky, crystalline or powdery residues; possible mould; battery leakage; pesticide history; or suspected lead, arsenic, mercury, asbestos or radioactive material.
Sealed packaging, stuck photographs or plastics, original surfaces of uncertain character, complex mechanisms, significant previous restoration or actions likely to alter authenticity.
Exceptional financial, historical, research or sentimental importance, particularly where an irreversible error would outweigh any cosmetic gain.
Chapter VII
These scenarios show how documentation changes the question from 'How do I fix this?' to 'What is happening, what evidence could be lost, and what response is proportionate?'
A flexible figure has become sticky around both lower legs while the painted torso remains dry. It has been stored against a clear plastic tray.
Temptation
Wipe it with household cleaner, dust it with powder or coat the surface to suppress tackiness.
Record first
Photograph the affected areas and packaging contact, note odour and paint softness, record whether residue transfers, and isolate the figure from other plastics.
Collector judgement
Tackiness may reflect plasticiser migration, coating failure, contamination or packaging interaction. Documentation turns a generic cleaning problem into a materials and compatibility question.
Orange staining surrounds the centre staples, but the pages remain attached and there is no obvious fresh debris.
Temptation
Replace the staples before the corrosion worsens.
Record first
Record both staple areas, centrefold alignment, staining, tears around holes, staple shape and insertion direction, and whether corrosion appears powdery or stable.
Collector judgement
Replacement may enlarge holes, detach pages and remove original binding evidence. Monitoring or specialist stabilisation may be more proportionate than cosmetic replacement.
The original box is deeply bowed, with a compressed internal insert and local pressure against the toy.
Temptation
Flatten the box under weight or introduce moisture to reshape it.
Record first
Photograph every panel, crease, flap and support; measure deformation; record printing, coatings, tears and pressure points.
Collector judgement
The safest response may be a custom support that removes pressure without attempting to erase the packaging's present shape.
A framed photograph appears locally adhered to the glazing after a damp event.
Temptation
Ease it away with water, heat or gentle force.
Record first
Photograph through the glass, map areas of adhesion, note cracks, lifting image layer and moisture history, and secure any loose glass.
Collector judgement
Attempted separation may remove the image itself. Documentation here is chiefly a route to stopping and briefing a photographic conservator.
Chapter VIII
A complete preservation record is chronological. Before-action evidence establishes the baseline; during-action notes preserve accountability; post-action records make change visible; later monitoring shows whether the response worked.
Record identity, condition, context, uncertainty, proposed purpose, alternatives, risks, authority and stop points before the object is altered.
Record dates, people, sequence, tools, products, concentrations, contact times, test results, unexpected findings, removed material and departures from the original plan.
Record final condition, additions, removals, deliberate non-treatment, residual risks, handling restrictions, storage recommendations and comparable post-action photographs.
Create new dated records. Retain the earlier condition report so the chronology of acquisition, storage, loans, treatment and monitoring remains visible.

Myth
Reality
Images may not show tackiness, looseness, odour, brittleness, movement or how detached parts relate. A useful record combines images with written observation, measurements and context.
Myth
Reality
A swab, solvent, eraser or adhesive test is already an intervention. Its location, pressure, contact time, result and delayed effect should be recorded before wider use.
Myth
Reality
A grade may summarise desirability or value, but usually does not locate damage, distinguish stable from active change, describe materials or preserve treatment evidence.
Myth
Reality
The enclosure may explain pressure, staining, abrasion, corrosion, odour or material transfer, and may itself be part of provenance, identity or completeness.
A post-cleaning or post-repair photograph cannot reconstruct removed deposits, original alignment, packaging relationships or starting condition.
A sales-style front image rarely records the reverse, interior, contact points, loose parts, labels or exact condition features needed for later comparison.
Calling every black spot mould or every white deposit corrosion can direct the collector towards the wrong treatment and conceal uncertainty from future readers.
Overwriting an earlier report or keeping only edited images destroys the evidence needed to establish when change occurred and what intervention altered it.
Preservation versus restoration
A clear record may show that better storage, restricted handling, support, isolation and continued observation are safer than cleaning or repair. It may also show that restoration is justified, but only after scope, acceptable visual change, materials, authority and stop points are agreed. Documentation preserves the option to decide; it should never be mistaken for permission to alter.
