Since version 1.0 scopus uses a config file ~/.scopus/config.ini to save credentials as well as directory names for folder that store cached files.

To change your key or to change directories for cached files, edit this file manually and import scopus again.

If the configuration file does not exist, scopus will raise a warning. To generate the configuration file, issue the command

>>> scopus.utils.create_config()

after import. scopus the prompts you for your credentials. Most users only need to provide the API Key and hit enter on the second prompt. If you have to use InstToken authentication, enter it in the second step.

Folder ~/ refers to your private home directory or home path. On many Windows machines this is usually C:/Document and Settings/<Your User Name>. In there you find a hidden folder .scopus, which is also the directory where scopus caches downloaded files.
