The article in the link above published by Maunder (2019) highlights the move for one Victorian public library to open 24/7, making it the first to do so in Victoria. This change reflects the community’s needs with many cited as being unable to access the library during traditional opening hours (Maunder, 2019). Likely the biggest security implication for libraries is potential misuse of facilities and resources (both physical and technological) as well as how patron safety is managed without staff present. Technology such as access cards and self-service capabilities help to mitigate these implications and facilitate the extended opening hours. Additionally, implementing induction and registration procedures ensures that patrons can use self-service facilities and are authorised to access the network. Library staff also note the presence of security cameras. However, as McBride (2017) highlights in a similar article, managing security in libraries is a delicate issue with a need to balance patron safety whilst avoiding making public libraries feel intimidating or unwelcoming due to security measures.

Good discussion of the security issues related to 24/7 library access, with the use of the literature to support your argument. Good point in regard to the delicate balance of security making patrons feel safe or intimated.
