The principal problem in the study of spiral structure is to reduce the data to a small enough number of pictures or numbers that can be easily comprehended. A new map has been produced, based on circular rotation, but the high probability of large radial motions makes it likely than any picture of spiral structure derived on current theories will be in error. New computer pictures have made it possible to see the structure of the outer arm, which has many cloud-like structures lying above it on one side, some reaching heights of more than 1 kpc. Some very weak extended features in the outer regions are described, and examples of holes and jets are discussed.
