PurposeThis article details the implementation of a live online chat service which was suddenly necessitated by the worldwide coronavirus disease 2019 (COVID-19) pandemic. The approaches used to train chat operators during this time inform both current and future training initiatives toward continuous improvement in this academic library setting.Design/methodology/approachChat transcripts from the period of March 2020–April 2021 serve as the dataset for this study.FindingsIn bringing a live chat service online during a global pandemic, chat transcripts from this period reveal 19.3% of all chat interactions related directly to COVID-19. The transcripts also reveal the types of questions, whether reference or directional, and these, combined with staffing patterns, indicate that staff were addressing reference questions more often than librarians. In addition, 25.2% of all transactions, whether by staff or librarians, resulted in tickets or referrals to hand off the question to a subject or functional specialist. These findings help to inform targeted face-to-face refresher training for chat operators.Originality/valueWhile bringing a live chat service online is certainly not novel, the impetus behind the quick setup was. This unusual circumstance allowed for an in-depth look at the nature of chat and its training requirements and limitations due to campus stay-at-home orders. It also provided a new understanding that influenced subsequent face-to-face trainings.
