Here is an information table, listing by GA #, the lectures given by Rudolf Steiner, with references to the name of the lecture (if we know it), city, GA number, code, and code notations (see the table at right for a listing of the codes and their meanings). To view a particular GA #, select from the pull-down menu. Informational messages pop-up when the pointer is placed over the name of a City, the GA #, or one of the Codes in the listing. If the lecture is on-line, the lecture name will be clickable. Note: GA's with over 50 lectures are very large pages — the largest is over 1200KB — so, a page selection option is provided for those GA numbers.
