Quick Start example on .retrieve_citation() not working

[Michael-E-Rose]

I use a working Scopus key in variable KEY which is enabled for the Citation Overview API. Trying to reproduce the Quick Start example I get the following error message:

>>> scopus = Scopus(KEY)
>>> pub_citations = scopus.retrieve_citation('84905286162')
Traceback (most recent call last):

Thank you for bringing this up.

As stated in the quick start page,

Please note that if you are searching the citation record for only one publication, you still need to put it in a list or numpy array.

So please try to put the scopus id in a list like this: ['84905286162'] and see if that works. My api keys are expired now and cannot test this feature at this moment.

Ah yes, that's how it works. I was reading it but then felt to simply repeat the example. You should maybe update the quick start page.
