Downloading to a citation manager
This feature enables you to download the bibliographic information (also called citation data, header data, or metadata) for the articles on our site. For additional assistance, please contact the World Scientific Customer Service Team.

Download bibliographic data for one or several articles: The Download to Citation Manager feature is available on book pages, journal article/book chapter abstract pages. On a search result page use the check boxes to gather metadata for several articles at once.

• Citation manager file format
  Use the radio buttons to choose how to format the bibliographic data you're harvesting. Several citation manager formats are available, including EndNote and BibTex.

• Direct import
  If you have citation management software installed on your computer your Web browser should be able to import metadata directly into your reference database.

• Checked: When the Direct Import box is checked (the default state), a dialogue box will give you the option to Save or Open the downloaded citation data. Choosing Open will either launch your citation manager or give you a choice of applications with which to use the metadata. The Save option saves the file locally for later use.

• Unchecked: When the Direct Import box is unchecked, the metadata is displayed and may be copied and pasted as needed.
