Abstract :
Influenced by the high penetration of
the Internet throughout the world,
Open Access (OA) publishing was officially
born more than 15 years ago. The
OA movement was begun to provide users
with free access to scholarly publications
for any lawful purposes.1 There are several
types of OA. In “gold OA” journals, authors
pay an article processing charge to publish
in the journal. In “platinum OA” journals,
authors do not need to pay for publication.
Hybrid OA journals are a combination of
subscription and gold OA models. Some
OA journals provide immediate free access;
others only after an embargo period
of up to 3 years, which protects their subscription
revenue.
