  • HighWire Press

  • "Science, Scholarship, and Internet Publishing: The HighWire Story" Syllabus Magazine, October 1998

    EXCERPT: "Scientists, scientific editors and publishers, scholarly society officers, and an enterprise unit of the Stanford University Libraries named HighWire Press have worked together over the past three and a half years to publish Internet editions of 70 influential scientific journals. Three significant accomplishments have resulted. First, there has evolved a mode of scholarly communication which serves readers, and facilitates research as much as it supports the clarity and validity of scientific discourse; this model has become a standard in Internet scholarly publishing. Second, an active community of scholarly editors and publishers has intensified the benefits of online scholarly publishing to the scientific, medical and technical communities at large. Third, the products of life sciences research in the advanced economies of Europe and North America are now more widely available than ever before, stimulating scientific and other cultural developments in other parts of the world."
