Although the primary aim at the outset of any conservation project is to stabilise and prolong the life of existing structures and formats, sometimes this is not possible and the need for safe access to the information they contain has to be given precedence. This remarkably shaped object certainly fell into this category.
This early C20th stationery binding contained bundles of correspondence in envelopes which had been adhered directly onto the leaves. Over time, the binding structure had become distorted from the thickness and number of inserted items attached to the textblock, resulting in this dramatically mis-shapen spine profile and ultimately the detached (and unfortunately lost) upper board. It must have seemed like a good solution at the time to use the envelopes as pockets to store the sheets of correspondence but ultimately this proved to be the death of the binding as a functioning housing method. In this case, the access to and safe handling and storage of the correspondence had to take precedence over the damaged binding.
The physical bulk of the inserts had also allowed extensive dirt deposits to accumulate on all the leaves – it was quite possibly the most consistently dirt-affected object I have come across. There was also browning and embrittlement of the edges of the leaves, again an effect of exposure to dirt and an unfavourable historic storage environment. This, and the weight of the envelope inserts, had caused extensive edge tears and chipping throughout the textblock. The information could not be accessed safely by the Librarian or readers, and the risk of the loose surface dirt affecting the largely clean documents in the envelopes was high. A decision was made in consultation with the Librarian to remove the correspondence bundles from the envelopes and house them separately from the binding. Whilst not ideal, this would provide safer access to the information, cut down on handling and allow an economic treatment solution.
The first stage was to clean every page and inserted item thoroughly, and the positive results of this can be easily seen below.
As most of the inserts were folded, flattening was required. Due to the nature of the inks used and the quantity of the sheets it was not desirable or feasible to use humidity to encourage the sheets to relax and flatten. Therefore, the inserts were unfolded and weighted between blotters over a period of time, with excellent results.
The flattened inserts were then rehoused in folders in boxes, allowing easy access to the information without the risk of damage to the correspondence collection. The binding and textblock were also stored in a box to maintain the record of their previous housing format.
