New Features and Announcements

Open Access

Open access status is provided across the Web of Science platform as a result of a partnership with Impactstory, a not-for-profit organization that recently launched a knowledgebase of Open Access (OA) content. This knowledgebase makes it possible to discover and link to legal Gold or Bronze (free content at a publisher's website) and Green (e.g., author self-archived in a repository) OA versions. This partnership improves discoverability and access to article-level OA versions not only by adding more links to OA content, but also by prioritizing the links to the best version of OA content when multiple versions of an article are available. Always consult the copyright owner for any re-use or licensing requests. You can learn more about OA on Web of Science at http://info.clarivate.com/openaccess.

The OA status of a document can be one of the following:.

OA Type	Descriptions
Gold	DOAJ	Articles published in journals listed on the Directory of Open Access Journals (DOAJ). To be listed on the DOAJ, all articles in these journals must have a license in accordance with the Budapest Open Access Initiative. Please consult DOAJ for their specific definitions. Consult the copyright owner for any reuse or licensing requests.
Gold	Other	Other Gold open access articles are those identified as having a Creative Commons (CC) license by Impactstory’s Unpaywall Database but are not in journals listed on the DOAJ. Most of these articles are from hybrid journals. Hybrid open access journals are subscription journals that include some open access articles. Keep in mind, identification of Other Gold as an indicator of Hybrid Gold open access articles is at varying levels of completeness, especially for newly published items. Consult the copyright owner for any reuse or licensing requests.
Bronze	The licensing for these articles is either unclear or identified by Impactstory’s Unpaywall Database as non-CC license articles. These are free-to-read or Public Access articles located on a publisher’s site. A publisher may, as a promotion, grant free access to an article for a limited time. At the end of the promotional period, access to the article may require a fee which can lead to temporary errors in our data. Keep in mind, you may find content that is incomplete, especially new content. Consult the copyright owner for any reuse or licensing requests.
Green	Published	Final published versions of articles hosted on an institutional or subject-based repository (e.g. an article out of its embargo period posted to PubMed Central). Consult the copyright owner for any reuse or licensing requests.
	Accepted	Accepted manuscripts hosted on a repository. Content is peer reviewed and final, but may not have been through the publisher’s copyediting or typesetting. Consult the copyright owner for any reuse or licensing requests.

A key advantage of the partnership with Impactstory is the ability to prioritize the open access links so the user sees the version of record at the publisher’s site first, followed by the final version at a repository, and then the accepted manuscript at the repository last. Only one open access link is provided.

Users may refine search results to identify these open access articles to ensure they can read the articles regardless of their library’s holdings.

Refining Results for Open Access

The Web of Science Refine Results panel offers two methods to filter a set of search results to show only Open Access content.

Using the Open Access filter in the primary Filter Results by panel near the top-left of the Search Results Summary page limits search results to all items identified as Open Access of any type.
The Refine Results panel on the left allows users to refine by open access type:

DOAJ Gold
Other Gold
Bronze
Green Published
Green Accepted

Analyze Results Redesign

A new intuitive visual analysis experience that makes it easy to grasp trends in large data sets at a single glance has been introduced. Users may interact with the visualization to provide more or less detail about the dataset or change the style of the visualization. To learn more about the data, users may click thru the visualization to see the specific records. Once complete, users may export the visualization to illustrate impact in a grant or tenure application.

Find Research Data

Research data is now discoverable within the Web of Science! Researchers may search for articles related to their topic within Web of Science Core Collection and then filter the results to find data available for re-use to reproduce to build on published results. Simply click on the Associated Data from the refine panel. Note: Only available for subscribers who have access to Data Citation Index.
