When I see large pieces of finished lumber, say a piece of 1" thick
oak thats a foot by 4 feet, it seems to be made of several pieces
joined together. Is this done because smaller pieces are cheaper or is
there some other reason? How are these joined together, is it by
bisuit joiner method or something more exotic? Will bisucit joined
lumber be as strong as lumber joined together in other ways?

It is more difficult to obtain wider boards than 100 years ago
narrower boards are glued together. There are various ways to join
wood but woodworking glue is usually strong enough. Biscuits do not
add much strength but they are good for alignment.
