# Browse Subjects

We first [introduced](https://blog.fairsharing.org/?p=159) our subject browser in November 2021, and it's one of our favourite ways of browsing records within FAIRsharing. In FAIRsharing, each record is tagged with one or more research subjects from our Subject Resource Application Ontology ([SRAO](https://github.com/FAIRsharing/subject-ontology)), which has more than 400 terms, organised in four top level classes: Humanities and Social Sciences, Natural Sciences, Engineering Sciences, and Subject Agnostic.

Our [Subject Browser](https://beta.fairsharing.org/browse/subject) helps you navigate the subjects hierarchy and find the standards, repositories, and policies relevant to you. You can also access the Subject Browser via the logo on the front page

The tool has three connected, interactive elements: a tree, a chart, and a paginated summary table. You can start browsing via either the tree or the chart views. Clicking on the tree view takes you to a view of the records in the summary table; navigating the chart simultaneously updates the tree view and will also take you to the summary table once you have chosen a leaf term (a term without a child hierarchy of its own).

**The tree view**, illustrated below, provides a traditional textual browser, showing the total number of records for each subject. Subjects can be expanded, collapsed and are selectable to display a definition of the subject and the associated records in a paginated table.

An example of **the paginated summary table** is illustrated below. You can either click on a row of the table and be taken to the associated FAIRsharing record or choose “Access All Search Options” from the top left of the summary table. Accessing all search options will take you to the full search page, giving you access to the full set of capabilities provided by our faceted search.

**The chart view**, illustrated below, is a graphical display of subjects in an interactive sunburst chart. As you explore the chart, the tree view also expands, showing the total number of records for each subject and enabling you to click on the relevant one to see the list of records in the summary result page.
