It appears that The Oracle yearbooks may have been published about every 4 years. These are the volumes that we have:

• 1901-1902 – our earliest volume. Available Online.
  This book states “The Oracle, First Annual of the Bremen High School by the Students of 1901-1902.” The classes of 1902, 1903, 1904 and 1905 are included in this volume.
• ???? If you have a volume printed between 1902 and 1908, we would appreciate a donation, or allow us to make a photocopy for our shelf.
• 1908-1911 Available as PDF (5 mb)
• 1912-1915 Available as PDF (6 mb)
• 1916-1919
  The 1916-1919 volume states: “Four years have elapsed since the Class of 1912 edited The Oracle, and the fates have ordained that the class of 1916 should produce the next. Of course it is not strictly a class affair. Without the co-operation of the entire student body and the faculty, it could not be a success.
