Elsevier provides a reliable API (thanks Elsevier!). In order to
retrieve non-open-access articles, you must sign up for a developer
API key:

1. Create a with Elsevier and `create a new API key`_.
2. Add the API key to a local config file.

The local configuration file (``.franklinrc``) should be placed in
your user's home directory::

  [Elsevier]
  api_key = <your-api-key-here>
