a number of pages. The leathers of the binding were calf skin and cowhide. The pH value of the leather samples was 5 and the results of the burning test indicated vegetal tanning. The books were divided into three groups: 1. defective books, where the leaves could be separated, 2. medium well preserved books that could be opened at several pages, 3. hardened incunabula where the leaves stuck together and the books could not be opened. The books were individually placed into plastic sacks and disinfected with paraformaldehyde purum fungicidal, while Basileum fungicide and insecticide was used on the wooden plates. Two methods were used to separate the leaves of the third group: 1. mechanical separation and 2. separation after moistening under a polyethylene foil. In the next stage of disinfection, 2% solution of Preventol CMK in ethyl-alcohol was injected into the books, and filter papers saturated with 10% solution of thymol in ethylalcohol were placed between the separated leaves. Wet cleaning was only applied on the incunabula the leaves of which had been separated. First the edges of the leaves were reinforced with 2% solution of Klucel M in ethylalcohol, and the coloured initials were fixed with the 5% solution of Regnal in ethyl-alcohol. Fatty alcohol sulphate was added to the cleaning water as a surface active matter. The paper became visibly cleaner yet the discolourations caused by the fungi could not be removed. Posterior gluing was made with 2% solution of Glutofix 600, and the leaves were reinforced with the partial or complete covering of the leaves with Japanese paper. The leather bindings were cleaned first mechanically then with lfatliquor. The hard leathers that had lost the structural water were softened: they were placed between two vetex foils, then a filter paper saturated with the 1:1 mixture of Glutofix 600 and licker, and, above it, a plastic foil were placed. A protective paste was applied on the leather bindings. Due to the mechanic weakness of the wooden plates, the deformations were not restored. The broken pieces were glued together with Planatol BB Superior. The solution of Selecton B2 was used for the cleaning of the metal mounts, then the Krefting method was applied. Each book was placed into storage box after restoration. The body of the book was packed into a filter paper and sometimes the body of the book, the leather binding, the wooden plate and the metal mounts were packed into a large, enduring envelope. As nearly every book body remained stuck together even after conservation, an uncustomary method was chosen for their study. First the topic of the books was determined, then the titles were compared first with the list of incunabula ofCsíksomlyó made in the 19th-20th centuries, then the fragments, of which high quality copies were made, were compared with items of the same edition preserved in Transylvanian (Batthyaneum, Gyulafehérvár) or Hungarian libraries (OSzK, EK, MTAK, Ráday Collection, Budapest). Altogether 26 incunabula were identified in 23 volumes during the scrupulous identification process. One volume was an edition in Hungarian language from the 17th century, it contained Káldi’s catholic Bible first edited in Vienna in 1626. The recently identified incunabula came from the most famous printing houses of the period: Augsburg, Basel, Bologna, Brescia, Hagenau, Nürnberg, Pavia, Strassburg, Venice.

Katalin OROSZ The elaboration of the collection preservation program of the National Archives of Hungary using the results of a statistical condition assessment Historians regard the National Archives of Hungary as the “memory of the nation” since the overwhelming majority of the documents of 1000 years of the history of Hungary is preserved here. The institution preserves more than 70 thousands document metres of archival material - parchment documents, manuscript and printed maps, designs, paper documents, various photographic materials, audio tapes, microfilms, electronic data media, and original paper, metal and wooden storage boxes in three buildings. The Archives has been dealing with restoration/conservation activities since 1949. The preventive preservation work started in the 1970’s. First it only meant the measurement of climatic conditions and the dusting of the depositories. Modem preservation can be dated from the 1980’s. The changes were initiated by the Department of Collection Preservation, which had a staff of 21 persons at that time. They were, however, random activities and did not extend to all the parts of the collection. The archivist did not always agreed with the suggestions regarding the solution of the problems. A complex preservation control was entered into the plan of the department in 1993, which was based on a regular inspection of the circumstances in all the departments where collections were stored. The inspection revealed that the climatic, technical and hygienic conditions of the depositories and the majority of the storage media were not up to the standard. Problems were found concerning the use and studying of archival materials as well, and it turned out that the knowledge of the colleagues regarding the protection of the collection were also incomplete. The inspection did not inform about the condition of the collection, only on their storage circumstances and use, yet it was instructive. The archival material that had been stored in packages was repacked into card-boxes with acid-free lining. Hair hygrometers were placed in the depositories. The document lending regulations were modified, and the documents were no more 142
