Konzervacija i restauracija orijentalnog rukopisa Al-Qāmūs Al-Muḥīṭ u Nacionalnoj i univerzitetskoj biblioteci Bosne i Hercegovine
Conservation and Restoration of the Oriental Manuscript Al-Qāmūs Al-Muḥīṭ at the National and University Library of Bosnia and Herzegovina

Summary/Abstract: Aim: The aim of this study was to carry out a comprehensive conservation-restoration treatment of the oriental manuscript Al-Qāmūs al-Muḥīṭ, focusing on the restoration of the binding’s functionality, paper stabilization and preservation of the original materials. Methodology: The methodology included an assessment of the manuscript’s condition, chemical analyses (UV fluorescence, water drop test, quick-blot test, spot tests, and pH measurement of the paper), as well as a series of conservation procedures: fumigation with butanol to remove biodeteriogenic agents, neutralization and alkalization with Bookkeeper solution tailored for water-soluble inks, mechanical cleaning using HEPA filtration and vulcanized sponge, impregnation with methylcellulose to stabilize the fibers, restoration of damaged areas using Japanese Kozo paper, and resewing the quires into the text block. Original leather covers were stabilized with Klucel G, while missing parts were filled in with new, hand-thinned calfskin. Results: The results after the conservation-restoration process show a significant improvement in the manuscripts’ chemical and mechanical stability: the papers’ pH increased from 4.6–4.9 to 7.7, mold spores and traces of biodeterioration were neutralised, missing parts of leaves were reconstructed and the manuscript regained its strength, functionality and aesthetic integrity. Wet cleaning could not be performed due to the solubility of the ink, which required the use of alternative, controlled methods. These applied conservation-restoration methods proved highly effective in treating manuscripts with sensitive inks, degraded paper and complex leather bindings, where the identification of original materials enabled the targeted use of modern stabilizing agents. Practical use: The combination of traditional techniques and modern analytical procedures produced results that contribute to the long-term preservation of manuscript heritage in Bosnia and Herzegovina and its accessibility for future generations. Clearly documented conservation-restoration procedures also add an educational dimension to the study, making it a valuable resource for young professionals and students, as well as a reference example of how contemporary approaches can be successfully applied in the protection of valuable manuscripts.
