Cretaceous gnetalean yields first preserved plant gum
Some liquid plant exudates (e.g. resin) can be found preserved in the fossil record. However, due to their high solubility, gums have been assumed to dissolve before fossilisation. The visual appearance of gums (water-soluble polysaccharides) is so similar to other plant exudates, particularly resin, that chemical testing is essential to...Roberts, Emily A. ; Seyfullah, Leyla J. ; Loveridge, Robert F. ; Garside, Paul ; Martill, David M.

The Use of Risk Management to Support Preventive Conservation
Risk management approaches have been increasingly used at the British Library to inform and support collection care decisions. This paper addresses the ways in which these methods have been used to address specific preservation issues at the Library, using appropriate case studies: rehousing the microfilm collection, adapting pest management protocols,...Garside, Paul ; Bradford, Karen ; Hamlyn, Sarah

Reframing Magna Carta – Comprehensive Planning and Pragmatic Outcomes
In preparation for the British Library’s exhibition to mark 800 years of Magna Carta, the Library’s copies of the charter, and three related documents, were reframed. There were several requirements: minimal intervention; allow re-treatability; fully show rectos and text; present the charters as documents rather than artworks. Comprehensive risk assessments...Garside, Paul ; Rogerson, Cordelia ; Moorhead, Gavin ; Matsuoka, Kumiko ; Duffy, Christina

The conservation of the burnt Cotton Collection
The Cotton Collection is one of the British Library's foundation collections and represents the single greatest known resource of medieval and early modern British history and literature. Its care and conservation are of great importance to allow access to the collection both now and in the future. The collection had...Beltran de Guevara, Mariluz ; Garside, Paul

An investigation of weighted and degraded silk by complementary microscopy techniques
A number of silk samples, comprising historic materials and modern surrogates, were examined by light, electron and atomic force microscopy, to determine the extent to which such assessments would allow the nature and condition of the materials to be determined. The integrity of these materials had previously been investigated using...Garside, Paul ; Mills, Graham A. ; Smith, James R. ; Wyeth, Paul

Categorizing tin phosphate/silicate-weighted silks on site by near-infrared spectroscopy
One of the most versatile instrumental analytical techniques for the non-interventive characterization of organic artefacts is near-infrared spectroscopy. In the case of textiles, methodology has recently emerged for assessing the condition of historic silks on site and a corresponding protocol that allows the simultaneous weighting categorization of silks would be...Garside, Paul ; Wyeth, Paul ; Zhang, Xiaomei

Use of near IR spectroscopy and chemo‑metrics to assess the tensile strength of historic silk
Silk is a culturally important textile, found in many artefacts of historic significance including clothing, upholstery, banners and decorations. However, it is a fragile material and is prone to deterioration via a variety of mechanisms, particularly after certain historically common processing methods such as bleaching and weighting. Therefore it is...Garside, Paul ; Wyeth, Paul ; Zhang, Xiaomei

Increasing the profile and influence of conservation—an unexpected benefit of risk assessments
Risk assessment prior to treatments, exhibitions or loans is vital to conservation, allowing potential problems to be identified and mitigated. After recent work on British Library ‘Treasures’, including the Magna Carta and the Lindisfarne Gospels, it became apparent that these assessments also served to significantly raise the profile and influence...Rogerson, Cordelia ; Garside, Paul

Looking beneath Dalí's paint: non-destructive canvas analysis
A new analytical method was developed to non-destructively determine pH and degree of polymerisation (DP) of cellulose in fibres in 19th–20th century painting canvases, and to identify the fibre type: cotton, linen, hemp, ramie or jute. The method is based on NIR spectroscopy and multivariate data analysis, while for calibration...Oriola, Marta ; Možir, Alenka ; Garside, Paul ; Campo, Gema ; Nualart-Torroja, Anna …
