Dear Alastair,
The percentage of the annual literatire that is openly accessible varies
from field to field. In High Energy Physics it is 100% and in chemistry
it is near 0%. There are about 2,500,000 articles published in 24,000
refereed journals acrosss all fields and languages each year.
Of this total, about 10% is available as full-text for free online.
Of that 10% about 2.5% gets there via open-access journals and the
remaining 7.5% via author open-access self-archiving.
