To comment on articles, select, or make annotations, the journal uses hypothes.is. The hypothes.is module is located in the upper right corner of the screen. To use it, log in to your hypothes.is account and comment or annotate your topics of interest. If you do not have an account, you can create one for free at: https://hypothes.is/signup.
Other value-added services include the reference generator that appears in the right-hand sidebar next to the articles, which allows you to select the citation style and generate the reference. You can also export citations in RIS and BibTeX formats for reference managers such as Zotero, Endnote, Mendeley, among others.
