# A very simple service that simply generates a "highlighted_link" to
# the Ulrich's periodical directory, if an ISSN is present.
# Does not actually look up first to make sure there are results, it's
# a blind link.
# config params:
# display_text: Name to put on the link. Defaults to "Periodical information". Can also be changed via i18n tranlsations.
