What eMargin is

eMargin is a free web tool for annotating text with others. Readers can highlight and colour-code passages, write notes, and tag words or sections. Annotations can be shared with groups to support discussion and combined interpretation, while live updates let users see one another’s changes as they work on a text. Search can narrow annotations by highlighted text, comment, colour, tag, creator, group, or date. Group settings determine which highlights are visible to members. The guide describes links from text to external resources such as the Oxford English Dictionary, Wikipedia, and WebCorp, along with printable text versions and annotation history. Birmingham City University describes support for streamlined Virtual Learning Environment integration. A project poster lists IMS LTI single sign-in and class-list import, naming Moodle, Blackboard Learn, and WebCT as compatible platforms. The service is described for educators and students across higher education, further education, secondary schools, and language schools. Its accessibility statement reports partial WCAG 2.1 AA compliance and notes keyboard navigation and low-contrast annotation colours as issues.
