Description/Abstract

The research access/impact problem arises because journal articles are not accessible to all of their would-be users, hence they are losing potential research impact. The solution is to make all articles Open Access (OA, i.e., accessible online, free for all). OA articles have significantly higher citation impact than non-OA articles. There are two roads to OA: the "golden" road (publish your article in an OA journal) and the "green" road (publish your article in a non-OA journal but also self-archive it in an OA archive). Only 5% of journals are gold, but over 90% are already green (i.e., they have given their authors the green light to self-archive); yet only about 10-20% of articles have been self-archived. To reach 100% OA, self-archiving needs to be mandated by researchers' employers and funders, as the UK and US have recently recommended, and universities need to implement that mandate.
