As a research librarian, my mission is to connect publication professionals with relevant and reliable information, literature, guidance, impact metrics, and copyright solutions. I am proficient with document delivery, proprietary research platforms, and have maintained searchable libraries for multiple therapeutic areas as EndNote libraries of PDFs and metadata for bibliographies. I also resolve copyright and open access issues and advise on journal and conference selection. As a member of the Special Libraries Association, Pharmaceuticals & Health Technology Division, I am passionate about accurate scientific communication. See my website PharmInfo pharmainfohub.com
