The basic copyright protection for material published before 1978 is 28 years. The duration is extendable if the copyright was renewed. It is likely that any copyright you have for material in the 50, 60's has long expired. See: http://www.copyright.gov/title17/92chap3.html § 304 . Duration of copyright: Subsisting copyrights.
Once the copyright is expired you are free to use the material.
