Outline Builder (back to top)

What is Outline Builder?


  • Outline Builder allows you to create a research outline by dragging and dropping text snippets and citations and adding your own notes.

How do I use it? 

  • The Outlines panel can be opened from the right side of a document.
  • Highlight text and left click to add it to your outline. Select the Add to Outline link or drag and drop the text into your outline.
  • The outline can be edited by adding headings and notes. Drag and drop can be used to rearrange outline sections.
  • You can also widen the panel and collapse the outline.
  • When you are ready, download the outline or email a copy in Microsoft Word.

KeyCite Updates: Citing With (back to top)

What is Citing With?

  • Citing With shows related cases that have a pattern of being cited together whether or not the cases cite each other.

How do I access it? 

  • Select the Cited With tab to view a list of all the cases that are commonly cited with the case you are viewing. Cases that cite to both the base case and a Cited With case are listed in a panel on the right.
  • Also, selecting the Co-Citing Button opens a panel that  allows you to review a list of cases citing both cases.
  • There is also a Full Page Button.
  • The base case is in Yellow; the cited case is in teal.

What filters are available? 

  • The Citing Relationship filter gives you three options:
    • No direct citing relationship
    • Cited by (case in the Cited With list is cited by your base case)
    • Cited to (case in the Cited With list cites your base case)
  • The Citing Proximity filter allows you to filter a Cited With list based on where both Cited With documents appear in relation to each other in a single document. These options include: 
    • String Citation (note that strings that begin with the Bluebook signals “quoting” or “citing” are not categorized as string cites)
    • Same Paragraph (includes instances where the case in a group that is preceded by the Bluebook signals “quoting” or “citing" and other instances of both citations appearing in the same paragraph)
    • Same Section (in the same section but not the same paragraph; sections are determined by the author of the document)
    • Same Document (also applies for documents with no sections)

KeyCite Updates: Overruled in Part (back to top)

How does the new flag look? 

  • The Overrule in Part flag has red and white stripes.  

What does it mean? 

  • This flag lets you quickly figure out if the grounds for overruling a case relate to the issue that you are researching.

How can I view the information in the case that relates to the Keycite flag? 

  • Selecting Overruled in Part from the Document Toolbar will take you directly to the relevant text, which will be highlighted for you. 

Graphical View of Search History (back to top

How do I find the Graphical View of my search history?

  • At the top of any page, select History.
  • The history can either be viewed as a list or graphically. (If you don't see these options, select View All.)

How is the Graphical View of history organized? 

  • Graphs are organized according to anchor events, such as searches and document retrievals. These mark the beginning of each visualization. Event bundles are used to group visualizations.
  • Events are listed in reverse chronological order.
  • Visualizations that bundle 10 or more events are highlighted with a blue line on the left side.
  • Listed for each event bundle are the date, duration, and number of related events.

How do I use Graphical View? 

  • When you select an event bundle, all steps are numbered according to the order in which you conducted them.
  • On the right side of the screen, there is a gear that can be used to emphasize high activity documents and minimize low activity documents. You can also download a copy of the display.
  • High activity documents are identified by tracking your actions on the site such as delivering, filtering, annotating, linking to other documents, opening key site tabs, and viewing resources.
  • If you select an item from the graphical history, a preview pane will appear with additional details, including notes or highlights you added or filters you applied.
