All risks to collections will be assessed, and measures put in place to control them. The aim is to stabilise and preserve the original physical object where it is damaged and/or at high risk of damage during storage and/or use.
Conservation practise is designed to arrest deterioration through understanding its mechanisms and applying scientifically-investigated treatments and preventive measures.
This is undertaken within an ethical framework to ensure that the intrinsic nature of a document is not altered, and that recognised professional standards are maintained.
Conservation includes examination, documentation, preventive measures, remedial treatment, and sympathetic repair where it is necessary in order to achieve stabilisation.
No attempt is made at restoration and any supplementary materials introduced as part of this process must be distinguishable from the original in order to avoid the possibility of compromising or falsifying the original material evidence.
Any approved treatment will be carried out in accordance with the following general principles of archive conservation:
- preventive measures will be taken to minimise the risk of damage. Handling training will be given to all staff and volunteers. Documents will be packaged, stored and handled in a manner designed to reduce both chemical and mechanical damage as far as possible
- documents/collections at risk of damage due to high demand and/or poor condition will be made accessible, where possible, by providing a surrogate copy such as a digital image
- wherever possible, items shall be preserved in the original form and condition that exist when referred for conservation, except where these significantly jeopardise their life expectancy or prevent access, in any suitable format, to the information they hold
- framed archival documents and photographs will be de-framed by conservation staff before being stored in the repository. This may be reviewed if the frame is deemed to be integral to the interpretation of the object. If an item is de-framed information pertaining to the object or its provenance that is attached to the backboard will be removed (as possible) by conservation and retained
- conservation treatment shall usually be restricted to consolidation and, if necessary, stabilisation to the extent that items can be digitised for access and last for a significant time into the future when stored in appropriate conditions and handled infrequently
- detailed conservation work will only be carried out on significant objects i.e. material with historic, symbolic or physical interest or value. Archive staff will be consulted regarding the importance of specific records
- information held within items selected for treatment shall not be lost as a result of this process or be placed at risk of future loss as a consequence of treatment
- all conservation treatment will be detectable and reversible
- a full conservation record will be kept of all interventive treatment. It will record the structure of the object prior to treatment, an assessment of its condition including the results of any diagnostic tests, a consideration of the options for treatment as appropriate, and a report of all treatments carried out and all chemicals, materials, and processes used. These records will be maintained indefinitely
- all materials and procedures used for preventive or remedial treatment will meet British/International Standards and/or current conservation requirements for suitability of purpose, in order to avoid introducing harmful components to documents, users, or the environment, and to maximise performance over the long term
- the range of items treated shall be determined by the facilities and resources available and the skills of the conservation staff; where appropriate, suitable training and development shall be acquired to maintain or supplement this range
- an intercept system is in operation for any member of the JAS staff to refer individual items or collections that they consider require assessment for conservation treatment
- conservation treatments will be approved after consultation between conservators and archivists. This will ensure that all available historical, scientific and technological information concerning the effects of treatment on the object have been considered
Conservation staff are expected to continually review their conservation practice in the light of on-going research and development in the field, and to interpret the conservation policy according to professional standards and best practice.
