• determine if said portion of a web document contains one or more predetermined words of interest to said user;
• and
• receive and store an entirety of said web document responsive to determining one or more words of interest are present in said document portion.

An enhanced web browser system capable of predictively browsing for web documents of potential interest to a user of a web browser system, said web documents containing words and being accessible through a linked address from said web browser system, said system comprising:

• a processor for executing program code;
• a user display for presenting information to a user;
• a user input device for receiving user input;
• a persistent storage device for storing data and information, including a user interest term list stored therein, said interest term list containing words of interest to the user;
• and a predictive interest-based browser program executable by said processor, said browser program adapted to receive a portion of a web document from a linked address, determine if said portion of a web document contains one or more interest term words, receive and store an entirety of said web document responsive to determining one or more interest term words are found in said document portion.
