It publishes 30 issues per year with four sections: news, opinion, features, and arts and entertainment. Historically, the arts and entertainment section was a special monthly edition but in 2022 became a part of the regular production when the sports section was removed and became a separate, online-only, publication Hi's Eye'' is unique among many student run newspapers in that it is weekly, and that it is completely self-funded. In September 2011, ''Hi's Eye
unveiled a new online version. Hi's Eye
aims to use the website to reach readers more often, and with more news that perhaps cannot always fit in the print version. The blog, which consists of weekly opinion articles, was created in May 2014. In September 2014, Hi's Eye'' created a Facebook Page, Twitter account, and Instagram account in hopes to reach a broader audience. ''Hi's Eye
