Abstract: A system and method are disclosed for displaying on a computer display a periodically amended document, such as statutes, regulations, city ordinances, or other legal rules. The system enables a user to easily view the currently effective version of the document, prior versions of the document, future versions of the document containing amendments already passed by a legislative body, and the amending documents (or acts) that have altered or will alter the document, and the changes made by the amending documents. The displays of amendments and document text can be carried backward or forward to display multiple cycles of amendments and resulting text, resulting in a complete history of the document. Additionally, the invention informs the user of the precise dates upon which amendments took effect, or will take effect, along with the beginning and ending effective dates for each displayed version of the document.

Abstract: A computerized system and method is presented for analyzing quotations made in a quoting document of text originally found in a source document. The present invention analyzes the quoting document for quoted text, searches the source document for that text, and stores the existence of the quotation in association with the source document. When displaying the source document, a list of text items that were quoted by another document is presented sorted by frequency of quotation. Quoted text is also highlighted when the original text of the source document is displayed. Hyperlinking is allowed between items of quoted text by the user and a list of documents that have quoted that text. From this list the full text of a quoting document may be displayed. The frequency of quotations taken from a source document can also be used to rank documents in search results.
