Abstract The present study examined the preservation practices for information resources in seven public university libraries in Tanzania. Convenient and purposive sampling techniques were used to recruit library staff and library directors respectively to participate in the study. Data were collected through questionnaires and semi-structured interviews. The quantitative data obtained from the questionnaires were analysed using the Statistical Product and Service Solution (version 20) software while the qualitative data from the interviews were analysed using the thematic data analysis method. Regarding the effective preservation approaches for information resources, the study established that binding, digitization, migration, and emergency preparedness plans were highly cited. The following were the recommended preservation approaches for adoption in public university libraries: digitization, refreshing, proper shelving, and cleanliness of all library areas, migration, technology preservation, and binding. From the findings, it was concluded that public university libraries have a variety of preservation approaches for both print and digital information resources. The study recommends that policymakers and the Ministry of Education, Science, and Technology should train librarians in skills that they can apply in preserving information resources using modern technologies.

Abstract There have been many treatises left behind by Persian master calligraphers detailing the different aspects of the art of the book such as book binding, types of paper, calligraphic styles and their importance, reed pens and cutting styles for calligraphy, as well as the construction of dyes, pigments, sizing, and of course, inks. While these treatises almost exclusively focus on traditional Persian crafts, the manuscript researched in this paper is dedicated to the western crafts and recipes which were gathered and translated into Persian by ‘Ali Ḥosseini, a 19th century Iranian scholar. Furthermore, he used the English terms of ingredients and transliterated them in Persian during translation, which can make deciphering the recipes very challenging for the average reader. The current paper focuses on the ink making recipes of the manuscript Kašf al-Ṣanāye‘ translated from European source.

Abstract “A very curious series of paintings in tempera on leather… are to be found at Buckingham Palace.” (Blunt 1946, 267). The 2017 Royal Collection Trust exhibition ‘Canaletto and the Art of Venice’ necessitated the examination and conservation treatment of eight paintings by the artist Marco Ricci (1676–1730). Marco’s artworks were unusually catalogued as ‘tempera on kidskin leather’, however it became apparent that internationally widespread confusion and inconsistency existed in the cataloguing of these artworks, complicating the understanding of these ‘curious’ paintings and the development of a conservation treatment approach. As in-depth material analysis was not possible, multi-collection and art historical research were combined with close observation to better understand the material nature and condition of this unusual group of paintings. The Royal Collection’s group of Marco Ricci paintings on leather is the largest in existence, with all 32 artworks presented in their original frames and it is suggested here that some exist in their original mounted format. This group is therefore the basis of much of the author’s current understanding. Despite presenting a consistent framed visual appearance, the project unearthed surprising variation amongst the Royal Collection works, serving to significantly supplement previous understanding of these paintings.

Abstract Following pilot testing of the effects of alkaline-based nanoparticles on modern parchment, the treatment was extended to historical parchment. This paper describes the application and impact of calcium hydroxide and calcium carbonate nanoparticles dispersed in (i) propan-2-ol and (ii) cyclohexane on a parchment book cover dated 1570. The cover showed signs of damage resulting from contact with iron gall inks and low pH values (∼4–5). Protocols for the damage assessment of collagen in parchment as developed in the IDAP project (Improved Damage Assessment of Parchment) were used to evaluate the impact of the conservation treatments on parchment. Preliminary results have shown that the application of calcium-based nanoparticles did not produce any adverse effects on the state of preservation of collagen. In addition, positive outcomes emerged: the pH was re-adjusted to a neutral value, a strengthening and consolidation effect was observed, and the nanoparticles exhibited a protective action upon artificial ageing of the treated parchment.

Abstract Ink corrosion on parchment is a phenomenon that, unlike its counterpart on paper, has so far been little researched. The same applies to the options for conservation treatment. In order to provide a guide for conservation practice as well as further research, five water-based treatment methods were examined: calcium phytate with pH 5.3 or 3.0, a 0.5% (w/w) solution type B gelatine, a 1% (w/w) solution of phytic acid at pH 2.2 and calcium phytate in combination with gelatine. These were tested on 70 specimens cut from on piece of buffed vellum and 36 specimens from an early modern deed on parchment that showed signs of ink degradation. After treatment and accelerated ageing, the samples were examined with colorimetry and ATR-FTIR spectroscopy and tested with bathophenanthroline for free iron ions. None of the tested treatment methods achieved a fully reliable inhibition of ink corrosion, but apart from a moisture-catalysed acceleration of degradation reactions, no adverse effects were observed either. Results from ATR-FTIR suggest that oxidation plays a more important role in damage related to ink corrosion of parchment than hydrolysis.

Abstract This article focuses on research into two ways of repairing holes found on parchment of Late Antique manuscripts. Their appearance and the reasons for these repairs are analysed and illustrated using the example of the Vienna Dioscorides, a Byzantine manuscript dated to 512. The reconstruction of the manufacturing method of thin Late Antique parchment prepared from lambskins shows clearly that these repairs were an important part of the production process and not subsequent repairs. Conservation of parchment may in some cases have a serious effect on the perception of this important technological evidence.

Abstract Novel approaches for reconstituted parchment from solely collagenous material are presented. The advantages and disadvantages of this infill technique are named, existing recipes which exclusively use collagenous material are analysed and modified. In a series of experiments, the possibilities to decrease or replace formaldehyde in existing recipes are explored and physical properties are investigated. As a result, two new recipes for reconstituted parchment are developed: the first one with a decreased amount of formaldehyde, the second one with potassium aluminium sulphate instead of formaldehyde. Their haptic and visual qualities are compared.

Abstract Parchment manuscripts form an important part of many historic collections. They are often found folded, with some displaying multiple fold patterns resulting from changing uses over their history. Parchment is a potentially fragile medium and folding can increase its susceptibility to damage, as well as hampering access and display. Treatment to address these issues may involve the relaxation of the folded structure, using humidification or a solvent such as propanol, and gentle pressing or stretching. However, this presents a dilemma – an inappropriately folded manuscript may be more prone to damage, but treatments require invasive interventions. This preliminary study has employed infrared spectroscopy and shrinkage temperature measurements to better understand the properties of folded parchment. It demonstrates that physicochemical changes can be detected at the fold and, to a lesser extent, in adjacent areas, compared to the bulk material, and that monitoring these changes allows the impact of different treatment methods to be assessed. This provides a basis for further research into the effect of both the original folding and of potential treatment methods, to inform conservation decisions and help ensure appropriate, effective, and sympathetic outcomes.

Abstract Objects made of dyed parchment are relatively rare in libraries and archives. When conservators dye parchment, they are essentially concerned with approximating the colour of the aged original material. Various methods are available today for dyeing parchment and other skin-based materials. This overview describes two methods in detail: staining with pastel chalk and dyeing with leather dye. Dyeing can be carried out before or after the application of an infill, the resulting advantages and disadvantages are briefly described. A look at the basis for decision for or against colour matching aims to motivate further discussion on this topic.
