<!-- text starts here --> <h4 id="scope">Aims and scope</h4> <p> <i>Algebra & Number Theory</i>'s inclusive definition of algebra and number theory allows it to print research covering a wide range of subtopics, including algebraic and arithmetic geometry. The journal publishes high-quality articles of interest to a broad readership, at a level surpassing all but the top four or five mathematics journals. </p> <h4 id="policies">Ethics and policies</h4> <p> Information about the journal's editorial principles, its policies for authors, the handling of complaints and appeals, and copyright and licensing can be found <a href="policies.html">here</a>. </p> <h4 id="peer">Peer-review process</h4> <p> This journal operates a single-anonymized review process (the names of the reviewers are hidden from the author). You can read about the peer-review process, including expectations and responsibilities for the journal and for reviewers, <a href="peer.html">here</a>. </p> <h4 id="schedule">Publication schedule</h4> <p> <i>Algebra & Number Theory</i> publishes 12 issues per year, for an expected total of about 2500 pages. </p> <h4 id="access">Access</h4> <h5 id="fees">Journal access and fees</h5> <p> Access to the journal is by <a href="http:/www.msp.org/publications/subs">subscription</a>.
