The conservation work behind our latest major exhibition, Propaganda: Power and Persuasion
Propaganda: Power and Persuasion, the first exhibition to explore international state propaganda from the 20th and 21st centuries, is now open in the PACCAR gallery at the British Library and runs until 17 September 2013. From the eye-opening to the mind-boggling, from the beautiful to the surprising, more than 200 posters, films, cartoons, sounds and texts reveal the myriad ways that states try to influence and persuade their citizens.
Work on an exhibition on this scale can begin anytime from three to five years in advance for the curators and others involved in the research and planning stages. Conservationâ€™s involvement begins around six months in advance, assessing the condition of items from the Libraryâ€™s collections that have been selected for inclusion by the exhibitionâ€™s curators. In the case of Propaganda, 195 items were assessed, 91 of which required conservation.
Over the following months the Libraryâ€™s conservators worked to document, conserve, mount, and prepare these items for the exhibition. For Propaganda, 30 posters and 19 leaflets required flush mounting; six bindings required minimal conservation; several items required minimal paper repair; and several other items required mounting included textiles, banknotes, postcards, and stamps. In addition, around 40 items borrowed from private collections required detailed condition reports on their arrival at the Library and most also required mounting.
This recipe book from the Libraryâ€™s collections required a book conservation treatment known as a re-back. New covering material is placed over the spine, re-forming the joints and head and tail caps, with the original spine covering adhered on top. A sympathetic colour match is chosen but there is no attempt to restore the missing areas.
Mounts, supports, and cradles must be made by hand for each of the objects exhibited, to ensure they are safely supported and displayed to the best possible advantage. This time-consuming and painstaking work is carried out by staff from both Conservation and Exhibitions to the highest possible standard.
This work has been identified by the British Library as free of known copyright restrictions. Above centre, a conservator stitches the handkerchief to the padded mount-board using silk thread. Above right shows a detail of the handkerchief after mounting.
This World War II-era silk handkerchief is a so called â€˜blood chit,â€™ which was carried by Allied soldiers infiltrated into Japanese-occupied territories in Southeast Asia. It required specialist textile conservation mounting techniques to prepare it for display in the exhibition. A bespoke padded mount-board was constructed by one of the Libraryâ€™s conservators using cotton fabric and swansdown and the scarf was invisibly stitched to this.

Books and other three-dimensional objects are supported on bespoke cradles. Cradles are made-to-measure for the individual book, supporting it at the correct opening angle for the pages that have been chosen for the exhibition.

Public information posters issued by Governments are among the most familiar forms of propaganda and there are many examples included in this exhibition. Above left is a poster from Communist Russia written in verse intended to promote good parenting of infants, and on the right is perhaps one of the most iconic images of war propaganda, J.M. Flaggâ€™s Uncle Sam recruitment poster.
Many of the posters displayed in the exhibition are usually housed folded in books or stored rolled. Before mounting they need to be flattened and this is usually done by placing them between heavy blotting paper and non-woven polyester webbing under a light weight for a period of time to allow them to relax.
After flattening, evenly spaced small tabs of lightweight but strong Japanese tissue are used all around the edges to hinge the posters to 100% cotton museum mount-board. Approx. 2mm of tissue is adhered to the back of the object, just enough to secure it, and the remainder of the tab is then wrapped around and pasted on the reverse of the mount board.
Smaller items such as paper bags, postcards, leaflets, and banknotes are usually mounted using archival polyester photo-corners instead of Japanese paper hinges. This type of mounting is suitable for temporary exhibitions but not for long-term storage.
There is very little turn-around time between exhibitions in the PACCAR gallery at the British Library. Staff from the Exhibitions department generally have only four weeks take down the preceding exhibition and coordinate build and installation of the new opening.
Exhibitions staff must work closely with Conservation, the Loans Registrar, and manage many external contractors to ensure that all construction work is completed and that all objects are safely mounted in their display cases.
Preventive conservation staff co-ordinate with Exhibitions to ensure that lighting, temperature, and humidity in the gallery are at optimum levels for preservation, and shortly before the opening the Libraryâ€™s collection salvage teams visit the gallery to prepare a salvage and disaster plan.
