Talk:Bibliographic record

Permanent physical location
In biblioteconomy, the phisical location of each code (paper copies, multimedia physical supports such Cd and DVD) is usually a public data and a permanent data. It can be changed uniquely in particular and specific situations. I haven't add it to the article in absence of a WP:reliable source, but the matter is regulated both by national laws and by international standards and best practices. Hope to find such a source in order to write a section about a basic metadata model, which is common to the existing formats. — Preceding unsigned comment added by 84.223.69.34 (talk) 16:40, 24 August 2019 (UTC)
