Open Access (OA) literature is digital, online, free of charge, and free of

most copyright and licensing restrictions. What makes it possible is the

internet and the consent of the author or copyright-holder.

OA literature is not free to produce, even if it is less expensive to produce

than conventionally published literature. The question is not whether

scholarly literature can be made costless, but whether there are better

ways to pay the bills than by charging readers and creating access barriers.

Business models for paying the bills depend on how OA is delivered.

OA is entirely compatible with peer review, and all the major OA initiatives

for scientific and scholarly literature insist on its importance. Just as

authors of journal articles donate their labor, so do most journal editors

and referees participating in peer review.

Altmetrics and open access – a measure of public interest

Altmetrics and open access – a measure of public interest

There is an interesting relationship between altmetrics and open access. One could even refer to altmetrics as open metrics. This is mainly due to the fact that altmetrics data uses open sources.

"For decades, the most common metric for evaluating research impact has been the number of times a research article is cited by other articles. This metric is sometimes represented by the raw count of citations received by the specific article in question or sometimes through an impact-by-association proxy – the number of citations received by the journal that published the article, summarized using a formula called the journal impact factor.

Citations are not the only way to represent the impact of a research article. A few alternative indicators have been the subjects of webometrics and bibliometrics research for years, including download counts and mentions in patents. However, as scholarly communication moves increasingly online, more indicators have become available: how many times an article has been bookmarked, blogged about, cited in Wikipedia and so on. These metrics can be considered altmetrics – alternative metrics of impact. (Appropriately enough, the term altmetrics was first proposed in a tweet [https:/].)"  Heather Piwowar
