NLM Serials data is available from:

  • NLM databases:
    • LocatorPlus (the NLM free online public access catalog; contains bibliographic data for over 1.5 million journals, books, audiovisuals, computer software, electronic resources, and other materials)
    • NLM Catalog (provides an alternate free search interface to NLM bibliographic data originally appearing in LocatorPlus; format similar to PubMed)
  • The NLM Data Distribution Program: Serfile, the subset of all serials in LocatorPlus or NLM Catalog, is available in either MARC 21 or XML format. Serfile has the most data elements available. Users of these data must arrange for their own Information Technology (IT) support to manipulate the data into a more human-readable format.
