The ODL object descriptions in this file describe the data fields in each row of the table. The table contains one row for each image file on this CD-ROM volume set. The image index table is formatted so that it may be read directly into many data management systems on various host computers. All fields (columns) are separated by commas, and character fields are enclosed in double quotation marks. Each record consists of 512 bytes, with a carriage return/line feed sequence in bytes 511 and 512.
