According to Wikipedia:
A joiner differs from a carpenter in that he or she cuts and fits joints in wood that do not use nails, usually in a workshop environment since the formation of the various joints generally requires non-portable machinery. A carpenter would normally work on site. Cabinet makers who specialise in manufacturing furniture are regarded as producing fine joinery.
The "joinery" and "joiner" usage is obsolete in the USA, although the main carpenters' trade union still calls itself the United Brotherhood of Carpenters and Joiners of America.
A "joiner" would generally produce items such as interior and exterior doors, windows, stairs, tables, bookshelves, etc.
I recently discovered that there is a piece of CLVB's work in exsistence. Rev. Eugene Brueggeman (son of Rudolph, grandson of Louis) has a bed that was made by him. He promises to share pictures which I'll share with you.
