To deal with continuous increases in the subscription fees of academic journals, libraries are now finding solutions by transitioning from journal subscriptions to open access publications. Although open access journals make articles freely available on the Internet, they commonly require authors to pay article processing charges. The Japan Alliance of University Library Consortia for E-Resources (JUSTICE) has developed a roadmap for converting to open access. For journal contracts during the transition period, transformative agreements, which include both subscription fees and article processing charges, have been introduced. For the sustainable circulation of academic information, university libraries and library consortia are trying to find effective ways to negotiate with publishers by collecting and analyzing use and payment data.

Elsevier conducted a world-wide event, Reaxys User Day, in order to share a variety of use cases of their chemistry database with users from all over the world. Both chemistry experts of Reaxys users and the representatives of Elsevier presented their unique use cases of Reaxys. The presentations were categorized in three sections: Design, Make, and Monitor. In the Design section, we shared the use cases for molecular designing. The Make section was about synthetic planning. In the Monitor section, we shared the use cases for patent research. In this paper, we report abstracts of presented use cases relevant to drug discovery and synthetic chemistry at Reaxys User Day.
