Magazine (archive)
A magazine is a space in an archive and is used to store registry or archive material. In doing so, registry material is to be kept just as carefully as archive material, since the archival evaluation can turn it into archive material. The magazine should have properties that enable permanent storage of the archive material. Some libraries have a library magazine that is usually not freely accessible to the library user.
Magazine types
The main types of magazine differ according to their content:
- Magazine for archival material ( archive material )
- Magazine for interim archival material
- Isolation magazine: documents infected with harmful organisms
- Incoming magazine: new additions to the archive
Size and setup of an archive magazine
The required size of a magazine depends on the amount of archive material to be stored, the expected growth and the shelf systems used. Sufficient cross ventilation is only possible up to a width of 20 m. If a magazine room is more than 40 m long, it should be divided into fire compartments. According to DIN 16245, files should be stored in special archive boxes on shelves. Card cabinets or hanging files are also suitable for documents of other sizes and types. The layout of the rooms and the load-bearing capacity of the ceiling are decisive for the choice of shelving. Mobile shelving systems enable a good ratio of usable area and storage capacity. You need a ceiling load-bearing capacity of at least 12.5 kN / m 2 . Free-standing shelving can be installed in angled rooms from as little as 7.5 kN / m 2 . Depending on the height of the shelving systems, there may be greater loads. According to DIN 1055-1 or 1055-3, a paper weight of 8.5 kN / m 3 can be assumed for layered files . Automatic high-bay warehouses and conveyor systems , as they are known from industrial logistics , are rarely used.
climate
The shelf life of the archive material depends primarily on the temperature and relative humidity . Different types of archive material require different climatic conditions. The selected values represent a compromise in order to enable the archive material to be used without long acclimatization.
| Archival material | temperature | Relative humidity |
|---|---|---|
| paper | 14-18 ° C | 35-50% |
| parchment | 2-18 ° C | 50-60% |
| Microfilm | 21 ° C | 20 - 50% |
| Color film | 10 ° C | 20 - 50% |
| Photographs, black and white | 18 ° C | 30-50% |
| Photographs color | 2 ° C | 30-40% |
| Magnetic tapes | 8-11 ° C | 15 - 50% |
lighting
Exposure to light damages many types of archival material, e.g. B. Paper and photo material. Since short-wave light is primarily responsible for the damage, no daylight should get into the magazine. Light bulbs are unsuitable because of the heat they generate. Instead, fluorescent tubes with reduced UV radiation (below 75 watts / lumen) can be used.
