The Book as a Form of Archival Material and Its Physical Preservation at the Historical Archives of Ljubljana – Gorenjska Unit in Kranj

Purpose: The research examines the physical preservation of books as a specific form of archival material. It aims to assess the condition of selected materials, identify the most common types of damage and risk factors, evaluate the suitability of storage conditions, and propose improvements.Methodology: The theoretical component draws on the compilation and analysis of specialist literature, legislation, professional guidelines, and previously published research. It examines the materials and structural components of books, together with the principles of storage and physical preservation. The empirical component includes an analysis of selected books held at the Historical Archives of Ljubljana, Gorenjska Unit in Kranj, and an interview with the head of the archives. A structured recording form was developed to document materials, bindings, damage, condition, and storage conditions.Results: Most of the examined materials are in fair to poor condition. The most frequently identified problems include mechanical damage to text blocks, spines, and covers, as well as changes to the paper, particularly yellowing, staining, and deformation. Storage conditions do not fully meet the specific requirements of books, particularly because of temperature fluctuations and unsuitable microclimatic conditions. Despite the use of protective enclosures, additional measures are needed to ensure long-term preservation.Discussion and conclusions: The research confirms the importance of understanding the material structure of books and providing appropriate storage conditions for their effective physical preservation in archives. The proposed measures include ensuring more stable microclimatic conditions, limiting the handling of fragile materials, and continuing to use protective enclosures. The findings emphasise the importance of preventive conservation that takes into account the physical characteristics and condition of individual books.
