The government-funded programme entitled “Acid Paper. Mass-Scale Recovery of Endangered Polish Library and Archival Collections” has been underway in Poland since 2000. The programme’s main participating organizations are the Head Office of State Archives (comprising four state archives) and the National Library in Warsaw. Other participants in the programme include: the Jagiellonian Library and University in Cracow, the Nicholaus Copernicus University in Toruń, and the Institute of Cellulose and Paper in Łódź.
The programme’s main goal is to start mass-scale deacidification of endangered 19th and 20th century holdings in Poland. This goal has been successfully pursued since 2003, resulting in the largest concentration of mass deacidification facilities in one country in Europe.
At present, two Bookkeeper installations have been purchased and are now fully operational, as well as six C-900 apparatuses from the Neschen company for deacidifying sheet documents. In each of the 6 mass conservation laboratories, the most damaged documents are restored and straightened following deacidification. In the first years of the programme various research projects focused on preservation issues were carried out. One of the programme’s main tasks was a preservation assessment of 19th and 20th century holdings in libraries and archives.
The survey was carried out in three archives and five libraries. Additional studies were focused on the microbiological aspects of preservation and mass conservation, including a study on air contamination in document cleaning areas.
Moreover a specialized research lab was up at the Chemistry Department of Jagiellonian University in Cracov. The lab is fully equipped and staffed for research focused on stability and degradation processes of paper, conservation methods, and effectiveness assessment of diverse mass deacidification technologies.
In the framework of the program, Polish State Archives are carrying out a broad action of microfilming and digitizing the archival record from the XIX and XX centuries. This microfilming and digitization program focuses on preserving information from documents in particularly bad condition. The “Acid Paper” Programme already started to give measurable effects: millions of single sheet documents and books have been deacidified, strengthened and properly preserved in envelopes and boxes made from materials with alkaline reserve. In the last year of the program, the Polish State Archives expect to fully synchronize digitization and deacidification of selected collections.
The “Acid Paper” programme was a unique and particularly instructive experience on the management, technical and the organizational levels.
