The Landesarchiv holds unique and irretrievable documents of the past such as manuscripts, books, charters and other cultural assets like seals, maps and plans.
Endogenous deterioration is the worst source of damage to these precious documents. They are greatly affected by temperature, humidity, mildew, mice, destructive insects as well as fire and flooding. The deterioration of paper poses a particular problem. Between 1850 and 1970 large amounts of acid paper had been produced. This paper or paper containing mechanical wood pulp ages visibly and quickly, goes yellow or brown and becomes fragile and brittle. These papers carry the seed of their own deterioration.
Therefore it is one of the most important tasks of archivists to preserve them and to guarantee their accessibility to posterity. To avoid further damage the archivists must concentrate on preventive measures of conservation. Thus preservation means not only restoration and microfilming, but also adequate storage and packing. In 1986 the Government of Baden-Württemberg set up its own restoration programme to stop effectively constant deterioration of the cultural assets kept in its Archives and libraries. The central part of this programme is the Institute for Preservation of Archival and Library Material, whose task is the conservation and restoration of the Land's intrinsically valuable cultural objects.
