The 036 field is used to record the original study number assigned to a computer data file by the producer.  This is an identification number for a data file, often assigned when the file was created and possibly embedded in the file as part of the recorded data.  Order numbers assigned by a distributor are recorded in field 037 (Source of Acquisition).

Input only the part of the file number that is known to remain constant on each issue.  If each issue has a different number do not input an 036 field.

Display constant

The introductory words Original study: are not entered in the MARC record.  They may be system generated as a display constant associated with the field tag.
