Thomas Cox papers

Identifier: NC218

Scope and Contents

The Thomas Cox papers consists of blueprint plans for mining structures and equipment.

The Thomas Cox papers has been arranged following the original arrangement of the creators of the records. The Cox Company filed drawings according to the type of drawing, for example, all the designs for plant buildings are filed in proximity regardless of company, as are those for steam power plants. Codes identifying the folder contents were written on the original folders; those codes have been transferred to the acid-free folders in which the drawings are now stored. The codes were composed of a letter and number; the letter represented the type of drawing and the number enabled sequential filing within each category.

Because of this filing arrangement, drawings for one particular company are scattered throughout the collection. Also, it appears that the collection is not complete and that some sections were not part of this gift.

Accompanying the collection was the original index to drawings, which included a list of the general contents. This index has been filed in the donor file; please ask for assistance if you wish to examine the index.
