"PUBLISHING", "SOFTWARE" or "RESEARCH"
The mark consists of the word "O'REILLY", with the apostrophe in a bright color (no claim is made to color) and the apostrophe is shaded gray to differentiate it from the letters of the mark. The design of a Tarsier touches the letter "O".
The lining shown in the Tarsier is a feature of the mark and is not intended to represent color.
