For those who enjoy frequent engagement with library systems in some form and/or have intimate knowledge of structuring digital files, we invite you to join us (@simoon and @manetta) during the Hold & Release Partyline (on Friday 10 + Saturday 11 of June at Varia, Rotterdam), where we will rethink library software, starting from Calibre. Can knowledge be held and released simultaneously? Subscription details and more information can be found here: https://varia.zone/en/hold-and-release.html
