An Interactive Open Access Journal of the European Geosciences Union

In the first stage, papers that pass a rapid access peer-review are immediately published on the Atmospheric Chemistry and Physics Discussions (ACPD) website. They are then subject to Interactive Public Discussion, during which the referees' comments (anonymous or attributed), additional short comments by other members of the scientific community (attributed) and the authors' replies are also published in ACPD. In the second stage, the peer-review process is completed and, if accepted, the final revised papers are published in ACP. To ensure publication precedence for authors, and to provide a lasting record of scientific discussion, ACPD and ACP are both ISSN-registered, permanently archived and fully citable.

Example of backward citing references.

Reference linking is available for all SPIE Journal papers published since 1999. Each Journal abstract page includes the complete list of references from that paper in HTML, with citation links as applicable. In addition, forward linking (citing articles) is now supported. Only subscribers can access this feature. Links are also provided to INSPEC and MEDLINE records. Proceedings papers have assigned DOI numbers and thus may be linked from other sources in the technical literature. Outbound reference linking from SPIE Proceedings papers to references cited within the paper is planned for the future. SPIE is a member of CrossRef.

CrossRef Forward Reference Linking
The SPIE Digital Library now also includes full CrossRef forward reference linking. In the past, forward linking was limited to citing articles published on the Scitation platform. With CrossRef-supported forward reference linking, new SPIE articles are deposited and stored in the CrossRef system. When a new citation is deposited from any other journal, SPIE is notified and a link to the new article is created even if the article is not published on Scitation.

In the Web 3.0 world, we will also start seeing heavily computed reputation-and-authority metrics, based on many of the kinds of elements now used, as well as on elements that can be computed only in an information-rich, user-engaged environment. Given the inevitable advances in technology, remarkable things are likely to happen. In a world of unlimited computer processing, Authority 3.0 will probably include (the list is long, which itself is a sign of how sophisticated our new authority makers will have to be):

• Prestige of the publisher (if any).
• Prestige of peer prereviewers (if any).
• Prestige of commenters and other participants.
• Percentage of a document quoted in other documents.
• Raw links to the document.
• Valued links, in which the values of the linker and all his or her other links are also considered.
• Obvious attention: discussions in blogspace, comments in posts, reclarification, and continued discussion.
• Nature of the language in comments: positive, negative, interconnective, expanded, clarified, reinterpreted.
• Quality of the context: What else is on the site that holds the document, and what's its authority status?
• Percentage of phrases that are valued by a disciplinary community.
• Quality of author's institutional affiliation(s).
• Significance of author's other work.
• Amount of author's participation in other valued projects, as commenter, editor, etc.
• Reference network: the significance rating of all the texts the author has touched, viewed, read.
• Length of time a document has existed.
• Inclusion of a document in lists of "best of," in syllabi, indexes, and other human-selected distillations.
• Types of tags assigned to it, the terms used, the authority of the taggers, the authority of the tagging system.

None of those measures could be computed reasonably by human beings. They differ from current models mostly by their feasible computability in a digital environment where all elements can be weighted and measured, and where digital interconnections provide computable context.

Libraries in the future will undertake local control, especially for long-term preservation and accessibility of digital as well as analog collections. Failure to embrace that role would cause libraries and librarians rapidly to lose relevance and value as Internet and other digital resources develop. Local control of collections is critical both to assure permanence and to provide a key degree of selectivity, which — contrary to the irrational exuberance of making everything available to everybody — is vital to providing service to communities of readers. Librarians need new tools, such as the LOCKSS system, to enable both persistence and selection of electronic information.
