"Literature should be freely and publicly available online [...] without financial, legal, or technical barriers." (Extract from the Budapest Open Access Initiative)
Open Access Strategies
The "gold road to open access" refers to the primary publication of research results in original open access journals. In the open access system, the same quality assurance standards apply as for publications in subscription-based journals. But other than in closed access journals, articles are worldwide freely and publicly accessible.
The number of open access journals is increasing steadily. In addition to original open access publishers (e. g. Copernicus), traditionally working publishers have founded open access journals as well (e. g. SpringerOpen).
In many cases, fees, so-called Article Processing Charges (APCs), are due when articles are accepted. The GFZ supports open access publications for staff members with its publication funds.

The green road to open access refers to the publication of quality assured text publications and other digital objects on an institutional or disciplinary document server (repository).
When publishing in subscription-based journals usually authors have to transfer exploitation rights to the publisher by signing the author agreement. However, many journals themselves, but also the German Copyright Act, allow simultaneous or delayed parallel publication on an open repository.
Common restrictions include:
- No use of publisher's version, only pre- or postprint (see FAQ: Preprint, Postprint, Publisher's Version)
- Reference to original publication
- Embargo, e. g. Open Access publication after 6-12 months
A good overview on publishers' copyright and self-archiving policies is listed by SHERPA/RoMEO: http://www.sherpa.ac.uk/romeo/index.php
If no publishing contract has been concluded for collections, the publisher acquires an exclusive right of use for only one year (§ 38 UrhG). After that, self-archiving is possible without restriction. In the case of conference contributions etc., publishing on an institutionally repository is unproblematic in many cases.

The publishers' offer to put an article - published in a subscription-based journal - open access immediately after publication is called "Hybrid Access". It is also known as "OpenChoice" or "Paid Open Access".
The are mainly three arguments against this publication model:
- In many cases self-archiving in the sense of Green Open Access is possible.
- Compared to usual Article Processing Charges (APCs) of Gold Open Access journals publication fees for Paid Open Access are disproportionately expensive.
- If the library already has subscribed the journal, the institution pays twice (double dipping): Publication fee for the article and subscription fee for the journal!
