When viewing CSD entries that which have a Digital Object Identifier (DOI) a clickable hyperlink to the original literature source will be available from the Author/Journal tab in the View Results pane. Articles are normally accessed via CrossRef (http://www.crossref.org) though links are also available where appropriate through the IUCr and LitLink. A subscription to the publication in question will normally be required to view the on-line article.
