The Association of Research Libraries (ARL) has released the final report from a study that ARL commissioned Ithaka to conduct, Current Models of Digital Scholarly Communication, by Nancy L. Maron and K. Kirby Smith, along with the database of exemplars that the study produced. ARL engaged Ithaka's Strategic Services Group to conduct an investigation into the range of online resources valued by scholars. Ithaka's findings are based on a collection of resources identified by a volunteer field team of over 300 librarians at 46 academic institutions in the US and Canada. Field librarians talked with faculty members on their campuses about the digital scholarly resources they find most useful and reported the works they identified. The authors evaluated each resource gathered by the field team and conducted interviews of project leaders of 11 representative resources. Ultimately, 206 unique digital resources spanning eight formats were identified that met the study's criteria. Highlights from the study's findings include: some of the resources with greatest impact are those that have been around a long while, innovations relating to multimedia content and Web 2.0 functionality appear in some cases to blur the lines between resource types.
