For the past six months I have been working on a challenging yet fascinating one-year conservation research fellowship at The National Archives on transparent papers. Today I’d like to tell you how readers at The National Archives are providing valuable information for this project via the Readers’ Transparent Paper Survey.

For the purposes of my project, transparent papers are defined as those papers for which transparency was vital for its intended role. For example, maps, overlays, copies of artistic designs, and engineering or architectural plans are relevant while pages of text on thin, and consequently transparent, paper are not.

The conservation of MH 47 in preparation for digitisation has been an intriguing and engaging experience due to the nature of the content and variety of paper-based materials within this group of records. The records are primary sources regarding conscientious objectors and appeals of exemption for the First World War.
Repairing a MH 47 record
While the majority of the records are standard forms of the Middlesex Appeal Tribunal, the group also includes minute volumes and hand written letters and photographs submitted by applicants as evidence of their claim. Thanks to the exceptional efforts of volunteers, the forms and letters pertaining to the appeal of each individual applicant have been sorted and placed in separate folders; this enables greater ease of handling, increased efficiency in completing conservation treatments and appropriate housing for long-term storage after digitisation.
The new Hull History Centre: an example of a transformational new archive building
It’s been a good few weeks for news of new developments for archive services across the UK. With the invaluable help of the Heritage Lottery Fund there has been a series of announcements of substantial support for some key projects which will ensure safe storage and high quality access for important collections. Among the recent good news stories are Manchester Archives+ , the project to transform the historic Central Library; West Yorkshire Archives Service’s Wakefield development and the funding for the Battersea Arts Centre. Experience from across the sector shows how new archive buildings can also reinvigorate services: acting as beacons to highlight the potential of the collections they hold, freeing up staff time from managing an inconvenient former home and offering scope for new activities where once the premises were too cramped to contemplate such work.
Designing a new or converted archive building is exciting, but also challenging. What goes into an archive building? The simple answer is: space for researchers, space for staff and space for collections. But exactly what that comprises depends on the space available, the collections to be housed and the activities it will host. The building needs to be well specified, to cover all the functions it will deliver, but not over specified, full of specialist spaces that are underused.
I’m going to start this post off by saying I really don’t like bugs! Little creepy crawlies give me the shivers and at home I have to have my husband take responsibility for evicting any spiders that might have strayed into the house. However, at work I have to resist the urge to freak out at the sight of insects as monitoring them is regularly part of the job. From my point of view I’m thankful it’s not something I’m directly involved in and my thanks go out to my colleague Hannah Clare for the text below.
Collection care team identifying insects
The Collection Care Department manages an insect pest monitoring scheme that uses over 120 insect blunder traps. These have no attractant pheromone lure and simply collect insects as they walk across the trap’s sticky surface; they are the most commonly used insect traps in museums, libraries and archives as they provide a reflection of the number of insects to be found in a particular area.
The traps are laid out in a grid-like fashion in all document storage areas at The National Archives and once every quarter a team collect all the traps and exchange them for fresh ones. Then the process of examination of the traps, identification of the insects, counting and recording all the data begins. To help us identify what type of insects we have on the traps, we use a set of images of the most common pests found in heritage collections and compare them to what we see under the microscope. We have to research any we don’t recognise to make sure we identify all our finds correctly.
Every morning when I turn on my computer, one of the first things I fire up is our environmental monitoring software so I can have a look at the temperature and relative humidity (RH) across our storage areas.

Every institution caring for any kind of cultural heritage collections makes it a priority to monitor environmental conditions such as temperature and RH (an expression of the amount of moisture in the air) where their collection is stored or displayed. This is because incorrect temperature or RH (too high or too low) can cause or accelerate the breakdown of materials, not only the paper and parchment support of documents but also other materials important to the portrayal of information, such as inks and the dyes used in colour photographic prints.
Monitoring environmental conditions has got to be, on the surface, one of the least interesting or celebrated parts of a conservator’s job, since it requires looking through and assessing long lists of numbers (we have over 180 different sensors in our storage areas), however, this kind of in-depth monitoring has proven truly invaluable to us here at The National Archives. We not only keep track of existing environmental conditions, but also collect data that will enable retrospective analysis. This data allows us to develop a better understanding of our building here at Kew so we can provide the best preservation environment possible for our records while at the same time ensuring that our solutions are sustainable. I’ve highlighted a couple of the projects that we’ve been busy with over the last few years below, including links to papers we’ve written that go into greater detail about the specifics of what we’ve done.

Collection Care is often about finding solutions to difficult problems and I addressed this theme in my last post when I talked about a project currently underway treating a particular series of photographs. Well, this problem-solving approach applies not only to our conservation treatments of the collection, but also to how we deal with things on a large scale – how we manage our collection.
What is in all the boxes?
One of the big questions we’ve grappled with as part of this project has been: what do we have? Oh, we know we have 11 million entries on Discovery, 13,000 series of records, etc. But to effectively manage the risks to our physical collection we need to know what types of materials we’re dealing with and how many of each we have. Tackling this question required extensive data gathering and some visual ingenuity.
As a conservator, my favourite archival material has always been photographs. There’s just something magical about photography’s mixture of chemistry and artistry that particularly captures my imagination. Therefore, I’d like to share one of the photographic projects we’re tackling in the Collection Care studio.
Recently, as one of our large, ongoing projects, we’ve been conserving and re-housing part of the COPY series. The COPY series comes from the Copyright Office at Stationer’s Hall and contains the forms of application for registration of proprietorship from 1837-1912 of different artistic, commercial or literary categories, one of which is photographs. Attached to most of the forms submitted are one or more photographic prints, providing a representation of what was being registered.

So here’s our challenge: We have 250 boxes each containing up to 600 forms and there is both physical and chemical deterioration to the forms and photographs.
The forms are housed in over-stuffed boxes, large photographs are folded to fit in the standard size boxes and handling has meant that the photograph was often bent to read the text on the form. The chemical damage includes colour change to the photographs or the forms due to adhesives used to secure the photographs to the forms, or due to transfer of the image of a photograph on to a paper form it has been in contact with.

Following the launch of The National Archives’ new online exhibition ‘To Her Most Excellent Majesty’ showcasing congratulatory addresses from Queen Victoria’s Golden and Diamond Jubilees, I’d like to share my experience of working on this project.

Did you know there are beakers and high-tech equipment for scientific analysis here at The National Archives?
I know that the image of a scientific laboratory is quite at odds with the images that normally pop into your head when you hear the word ‘archive’, but all the same they are vital to the work that conservators undertake here every day.
Our conservation lab provides the facilities for us to evaluate materials for use in conservation, to prepare materials for use in conservation treatments and to carry out those conservation treatments that require the use of chemicals in a safe environment. To give you a little taste of the many things we do in the lab, here are a couple of examples of some of the material testing we’ve been up to lately:
Should we replace those old map folders?
Beakers of paper samples for pH testing
As part of making a case for a re-housing project, one of our conservators is pH testing both the existing map folder materials and the new material she suggests it is replaced with. This will enable her to quantify the benefits of the project. If the current material is significantly acidic, and the new material shows an alkaline buffer, it can help give a justification for her choices in the project.

On your visit to The National Archives, you get your reader’s ticket to order up the documents you are interested in seeing but, after entering the document references into Discovery, a document comes up as ‘unfit for production’. So, you wonder, what does that mean?
Unfit document - Detail of damage to an unfit document
Items designated ‘unfit for production’ are in such vulnerable physical condition that producing them would present a risk to the document – unfit documents could be extremely fragile, they could be blocked (all the pages stuck together in a volume or a roll), or perhaps they could be damaged by mould. These are the documents that, when you open the box, you immediately jump to put the top back on and quickly hide it at the bottom of the pile, hoping that it will miraculously disappear!
