Photography, reprography and microfilming

Responding to internal as well as external mandates, the Photo and Reprography Service of the NL duplicates documents from the NL collection with the utmost care and precautions to preserve the original document. The mere fact that such a service exists in-house can be construed as a conservatory measure: original documents do not have to be transported elsewhere consequently the risk of losing and damaging them in the process is greatly reduced. The Photo and Reprography Service is responsible for all matters relating to microfilming at the NL. Newspapers are the medium most threatened by the deterioration of paper. Lignin, which is contained in wood-based paper, degrades into organic acids, turns the paper brown and accelerates its deterioration.

The NL has therefore decided to microfilm its newspaper collections in order to conserve them for future generations. The lifespan of a black and white microfilm is estimated at 500 years making the microfilm an adequate alternative medium. Priority is given to certain newspapers according the following criteria: the state and the frequency of use of a newspaper.

Since 1997, the NL has been involved with other institutions in a project to coordinate the microfilming of newspapers (MIKO project). These joint microfilming projects make it possible to spread the costs, complete collections and prevent microfilming the same collections more than once. A diazo copy (produced from the original microfilms) is available for consultation on open-access at the NL.
