The records of the Maryland Steel Company of Baltimore County collected by the Bethlehem Steel archives were limited to those of the Marine Department and a few corporate papers. There is substantial coverage of the steel works and company town in Accession 884, the Frederick W. Wood Papers.

The Marine Department records include cost books, specification books, and job files. The cost books contain the accounting for materials and labor by individual vessel contract. The specification books are printed specifications giving material standards and dimensions. The job files contain mostly routine correspondence relative to individual contracts.

There is a run of minutes and related papers for the company's annual meeting of stockholders following its transferal to the Pennsylvania Steel Company of New Jersey in 1901. Minutes for a special meeting of stockholders and directors from June to July 1919 cover the dissolution of the company.
