JSTOR, the not-for-profit organization that creates and maintains a trusted archive of important scholarly journals, provides free subscriptions to any academic or not-for-profit institution in Africa. If you are part of an academic institution or non-profit that is interested in obtaining a subscription to JSTOR, contact Danielle Waugh at danielle.waugh@jstor.org. I looked at the list of institutions currently benefitting from this in Africa, and there are no Liberian institutions on the list.
