Stan zachowania szesnastowiecznych druków biblijnych z kolekcji Biblioteki Fundacji Wiktora h. Baworowskiego we Lwowie

Abstract

Evaluation of the preservation state of sixteenth-century biblical prints from the collection of the Count Wiktor Baworowski Foundation Library in Lviv was conducted using the descriptive method from the autopsy. The evaluation of each volume was additionally extended by the assessment of the degree of acidity of the paper, biological damage; a simple bending test was also performed. Damages to the binding, book structure and old print block were assessed separately. After the partial assessments, the copy was classifi ed into one of four categories. 17 preserved copies were tested, of which 10 are in poor condition and should be taken out of service. The paper is in very good condition in terms of mechanical strength. The books require no deacidifi cation. On the basis of a visual analysis of the biological damage, it can be concluded that the book collection was not stored in optimal conditions in the past, as evidenced by the damage caused by insects and fungi, as well as stains and streaks on paper.
