A place where historical documents or materials are stored.
Also: documents or materials that have been archived.
"There are two main archiving options that all open access journals should consider—“dark” archives and publicly accessible archives.
- Dark archives: A dark archive is a private archive that cannot be accessed by any users. The purpose of a dark archive is to secure access to content in the event of a publication being lost or discontinued. Dark archives will only release content when there is a “trigger event” such as confirmation that a journal is no longer in publication. Commonly used dark archives include Portico and CLOCKSS.
- Public archives: As the name suggests, public archives are openly accessible to users. Public archiving options include preprint servers, public archive databases, and institutional repositories. Some well-known public archives include SSRN, arXiv, PMC, and Deep Blue.
Many archives have specific article formatting and deposit requirements to ensure that they can properly process content. In the past, we’ve written about how indexes must ingest conent in machine-readable formats in order to parse it, and archives are much the same. Most archives require journal publishers to deposit machine-readable, front-matter XML metadata files into them. Front-matter XML files contain the front matter of the article-but do not include the article’s actual body text."
