Historical holdings in a new guise: Almost 1,500 German-language books that were cleaned, deacidified, restored, or rebound and protectively packaged as part of the project "Nimm ihm Saures!" (“Take its Acid!”) have returned to the library of the Institute for German Culture and History of Southeastern Europe.

The holdings
Text
The 850 volumes and 600 capsule writings date from the period between the beginning of the 19th century and 1990, when acidic paper was regularly used. Over the years, the acids cause the paper to yellow and lose its elasticity; eventually, it becomes brittle and is easily torn. In Eastern and Southeastern Europe, the production of acidic paper was more widespread than in Western Europe. The year 1990 therefore has a double significance as a year of upheaval. On the one hand, it heralded an opening to the West and thus new standards in paper production. On the other hand, many publishing houses, often without a clear legal successor, had to close down during the politically difficult times, making it particularly difficult to replace printed products.
Conservation and restoration measures carried out
Text
Not only the paper quality, but also the bindings of the selected works made conservation and restoration measures necessary. Many volumes were bound only in a paper envelope or not at all. Others were only held together by metal staples – these had to have the metal removed and were re-stitched to prevent rust damage. In some books, missing sections of pages had to be added and tears repaired. Other damage, such as that caused by mice, required much more complex paper restoration work.
 
In order to prevent their imminent decay, to enable their use and to ensure the preservation of the originals, about 300 kg of books had to be cleaned, de-acidified and partly treated for conservation. The highest priority in all restoration measures was always the greatest possible preservation of the original.
 
In the next step, major restoration work was carried out on 374 volumes. New bindings were made and spines were repaired that had been damaged by incorrect storage or handling. For particularly beautiful or rare books, custom-fitted slipcases were made of acid-free cardboard to protect them on the shelf from abrasion by neighboring books. 600 rare capsule typefaces , i.e. thin booklets of less than 100 pages, were packed in acid-free dust jackets and are now stored horizontally in special archive boxes for more gentle storage.
 
For those books that could not be de-acidified due to the condition of the paper, but also for copyright-free books from the project, digitization is now being increasingly pursued, in cooperation with the Bavarian State Library and other organizations. Thanks to the generous support of the CEC with a donation of more than €70,000, the rare books will be preserved as originals for centuries to come through de-acidification and restoration in the IKGS library. They will soon be made accessible worldwide as digital copies.
