Oxford

Oxford was a single-sided brand produced by several manufacturers (including Columbia Phonograph Co., Universal Talking Machine Manufacturing Company and Victor Talking Machine Co.) for mail-order sale through the Sears Roebuck & Co catalog.

Oxford discs replaced Sears' earlier Harvard Disc Record, and were produced and marketed between 1906-1916. All issues duplicated material that had been issued earlier on Columbia or Zonophone Record, and were anonymous. In 1916, Oxford discs were replaced with records bearing the Silvertone label, in keeping with Sears changing the name of its phonograph line from Oxford to Silvertone.
