Beginning with the January 2007 issue, Pacific Science joined the BioOne family of journals. This means Pacific Science will be full text archived (PDF and HTML) BioOne alongside other prominent journals such as Bioscience and Evolution. Through BioOne, Pacific Science papers are freely accessible to researchers through most research libraries around the world. Pacific Science is also now an "ISI journal" listed in the expanded Science Citation Index. Pacific Science is also now fully indexed at Google Scholar.
