Abstract :
We announce, with both pride and trepidation, that with this issue this publications assummes a bimonthly status. Next, the appearance of a new category of communication, called a Concise Paper, in the last issue. We have found a real need for this type of item, which falls somewhere in between the formal Contribution, which has major significance to the development of the art, and the Correspondence item, which reports some smaller finding or correction to previously published material. Lastly, we have been receiving a few knocks (and, occasionally, kudos) for the recent technical content of these Tranactions. These have not been formal "Letters to the Editor" for publication, but sincere personal criticism of judgment in the selection of material that has been published. Each such communication has been taken up with the Technical Committee that reviewed the original material before publication and recommended its use. This discipline, while not always pleasant, will in the long run serve to strengthen our editorial policies and procedures.
