What is typically revealed to the reviewer in a single-blind peer review?

In a single-blind peer review, the identity of the author is typically revealed to the reviewer, allowing the reviewer to evaluate the work with the context of knowing who is being published. This approach is designed to provide reviewers with sufficient background about the author's expertise and previous work, helping them provide a more informed critique.

The anonymity allows for an easier assessment of the content without the pressure of bias against the author's identity, often resulting in a more constructive and honest evaluation. However, it is important to note that while the reviewers know the author's identity, the authors do not know who the reviewers are, which helps to maintain a level of impartiality in the review process.

In contrast, the author's full credentials may not always be disclosed—reviewers might get relevant background but not necessarily all credentials. The reviewer's comments are part of the feedback given to the authors post-review, and peer review guidelines are generally not revealed to reviewers in a way that would identify individual authors.
