DSM-III (1980), DSM-III-R (1987), and DSM-IV (1994) introduced and refined a new classification that considered recent discoveries about the biochemical and post-traumatic origins of some types of anxiety.
Doctors and therapists use the DSM-IV codes to describe the features of specific mental disorders and distinguish them from similar afflictions. These codes allow information to be relayed between doctors and therapists both concisely and precisely, and helps avoid misunderstandings and errors.
The DSM IV Diagnostic manual was first published in 1994. The DSM IV - TR is a text revision published in 2000. So the most current edition is indeed the DSM IV - TR. The DSM V is due in 2012 and may be very different from the current style. See http://www.psych.org/mainmenu/research/dsmiv/dsmivtr.aspx for more info.
The DSM-IV is written and revised by the American Psychiatric Association.
The DSM-IV has around 900 pages in total.

DSM-IV codes are used specifically for classifying mental disorders for medical records and billing. ICD-10 codes are the newest set of medical billing codes that will need to be used beginning October 2015.
In the DSM-IV, there is no specific diagnosis or category known as a "midnight personality." It could be a colloquial or nonclinical term that is not recognized within the diagnostic criteria of the DSM-IV.
