Both the Hawaiian and Pacific Collections have a great many historic newspapers, dating from the 19th century through present. Many are in microfilm, and most have not been indexed, meaning that if you're searching for a specific event, your only option may be to go to the microfilms and begin reading papers dating from the period you're interested in. However, some have been digitized, and in these cases are searchable and readable online.

The Honolulu Weekly was published between 1991-2013. For many in Honolulu during these years, especially prior to the advent of the Internet, the Weekly was a welcome alternative to the Honolulu dailies, offering a fresh take on Honolulu's music and culture scene, and focusing on astutely selected social and political issues of the day. The paper’s weekly publication cycle and long-format cover stories often allowed writers to explore topics at a depth the daily newspapers were unable to, while also encouraging writers to go beyond simple reporting and into a more nuanced analysis.
