Since the last world war, there has been an increasing interest in preserving and utilizing archival material in Iran, but, despite several attempts, appropriate institutions have not as yet been established for this purpose. To substantiate their viewpoints, researchers often have to wait long periods before gaining access to the desired archival material. This, of course, does not imply that documents were not preserved in Iran. Throughout the entire Qajar period, the existence of a document chamber at the imperial court, in which documents of unequal value were preserved with reasonable care, indicates that the preservation of archival material is a long-established custom.
There are also private archives of considerable interest, but unfortunately these materials were preserved for long periods only if they had legal or administrative importance. For example, the contracts for real estate transactions, or designations of waqf properties, were carefully preserved by heirs or distantly entitled parties, while documents of only practical interest usually disappeared within two or three generations.
