Omslagsnummeret

Omslagsnummeret is a term used in Swedish publishing and library practice to refer to the number printed on the cover of a book or periodical that identifies a specific edition or printing. It serves as an auxiliary identifier alongside more formal cataloging marks such as ISBN, rather than as a universal standard.

The primary purpose of the omslagsnummer is to differentiate between printings, reissues, or issues of the same title. It helps publishers, distributors, booksellers, and libraries track stock, manage inventory, and ensure that customers receive the correct edition. The number may reflect the release sequence, year, season, or other edition-specific details held by the publisher, and it is often found on the cover itself, sometimes near the price, barcode, or imprint information. Formats vary and there is no single standardized form for omslagsnummeret.

In cataloging practice, the omslagsnummer can be noted in bibliographic records to inform staff about edition variations. It is typically considered supplementary to the ISBN, which remains the primary international identifier for titles and editions. The term is especially common within the Swedish book trade and archival contexts, though similar concepts exist in other markets under different names.

Overall, omslagsnummeret is a practical tool for edition differentiation used mainly within production, distribution, and cataloging workflows. Its relevance has diminished somewhat with the dominance of ISBN, but it remains a recognizable element in historical and region-specific publishing records.
