The shelf meters (abbreviated: Rm ; also running meter , lm ) is a unit of measurement in library journals , archives and in storage . One meter of shelf corresponds to a storage area one meter wide; The depth of the surface and the height of the storage space are not taken into account. Another definition commonly used in the industry is that a running meter of files consists of twelve DIN A4 standard file folders with a spine width of 8 cm in a row . In standard shelving systems, these fill exactly one compartment 1 meter wide.

Archival materials and book stocks are often not measured according to the number of items, but according to the space they take up on the shelf . In the case of archival documents, one of the reasons for this is that an exact counting of the amount of documents stored would be too time-consuming. In the case of archival documents, the lined-up files or boxes or containers in which the files, documents and the like are measured are measured. Ä. are located. The number of documents or books that one meter of shelf contains therefore fluctuates greatly.

An alternative unit of measure is the file unit (AE) or capsule (Kps). In the case of books, the shelf meters are measured across the back .
