1. A method comprising: entering a source digitized text into a memory of an information technology system; delineating the source digitized text into a plurality of segments by a user; associating a first selection of the segments by the user with a first tag; individually assigning by the user a unique sequence number to each segment of the first selection, whereby each segment of the first selection is associated with a unique sequence number within the first selection; associating a second selection of the segments by the user with a second tag; individually assigning by the user a unique sequence number to each segment of the second selection, whereby each segment of the second selection is associated with a unique sequence number within the second selection; receiving a user command to proceed to thereafter sequentially render segments associated with the first tag; generating a first node record and associating the segments associated with the first tag with the first node record; associating the first node record with at least one other selected segment associated with the second tag when at least one of the segments associated with the first node record shares the second tag; sequentially rendering each segment associated with the first tag node record in accordance with the order of each individually assigned sequence number of each segment of the first selection until the associated selected segment is rendered; receiving a user command to sequentially render segments associated with the second tag; generating a second node record and associating segments associated with the second tag with the second node record; sequentially rendering segments associated with the second node record in accordance with the order of each individually assigned sequence number of each segment of the second selection.

The method of claim 1 , wherein at least one additional segment of the segments is associated with both the first tag and the second tag.
