While churches were historically built with the altar at the geographical east end of the building, liturgical orientation is not always connected to the geographical orientation. If you stand in the aisle facing any main altar, that is “liturgical east.” From the earliest days up until a few years after the Second Vatican Council, the priest faced “liturgical east” while saying Mass (or in Latin, ad Orientem). The main ambo or pulpit was at “liturgical north,” meaning to the left of the altar when facing it, and this was called the “Gospel side” because the Gospel was read from the “north” or left end of the altar. The Epistle was read was at the “liturgical south” end of the altar, and the presider’s chair was typically on this side of the sanctuary. It stands to reason that the back of the nave was “liturgical west,” hence terms like the “west front.” The majority of churches in my diocese have the altar at the geographical north end of the building, but this is still considered “liturgical east.”
By the way, there are three kinds of bookstands: a lectern is a free-standing stand commonly found in classrooms (often confused with a podium, which goes under a lectern to elevate it and the speaker); an ambo is an elevated, solidly-built lectern approached by stairs; and a pulpit is an ambo with side panels which partially enclose the speaker.
