SciELO has released SciELO: 15 Years of Open Access.
Here's an excerpt:
The creation of SciELO 15 years ago and its further development were driven by two innovative and pioneering approaches: first, the indexing of national quality journals to complement international indexes and the publication of the full texts with free access on the Web in the modality known today as the "Golden Road", which took place about four years before the launch of the Budapest Declaration that is internationally agreed to as the beginning of the Open Access movement; and, second, the cooperative convergence of independent publishers, editors and national research agencies around a common objective to increase the visibility and quality of journals (Packer 1998; Meneghini, 2003; Packer 2009). During this development, SciELO became a standard of quality for the journals it indexes. As of June 2013, the SciELO network covers 15 Ibero-American countries plus South Africa, with each country publishing a national collection of journals in the network. There are also two multinational thematic collections in the network. Together these countries index about one thousand journal titles that publish more than 40 thousand articles per year. To date, the network has published a total of more than 400 thousand open access articles that receive a daily average of over 1.5 million article downloads, 65% as PDF files and 35% as HTML files.
