To begin, we mine a corpus of astronomy articles for external web  links. By ``external web link'' we mean: any outgoing link embedded in the  final published version of an article (e.g., its PDF or HTML format)  which points to an online resource in the \url{http} http  (or \url{https}) https)  URI scheme. The purpose of this exploratory analysis is to assess whether  astronomers use links within articles to point to datasets and related  supplemental data resources.
