You need to select good Open Access journals (e.g. PlosOne) from litter journals (I prefer not mention them, but generally you receive dozens of spam announcements per day from them). In addition, in Europe, any research funded by a public body must be published in open access or make it available through systems like ResearchGate or OpenAire. In these cases, the papers are published in SCI journals, but make publicly available by including the last accepted version

The open access publications have really flooded the litrature in each subject often with articles that would otherwise not accepted for publication in any reasonable journal. There should be a mechanism to filter out these journals from the scientific database. Actually the open access publications are sometime more widely circulated due to easy access via google etc. This needs serious thinking else lot of junk litrature will be created.

But to keep control on which open access is good and which is dubious remains a challange.

Yes, that's true, but not so difficult

I think it would be desirable to publish in journals with impact factor. This should ensure the minimum quality requirements for a scientific work.

 Dear Irene Fernandez

The most important advantages and disadvantages

Advantages

1: Free for all

2: Increased readership

3: Access for researchers in developing countries

Disadvantages

1: Publication fees

2: Lack of quality control

3: Sustainability

Some argue that traditional paid access models ensure publishers are adequately compensated for the substantial role they play. Whether open access models can sustainably support the research publication infrastructure in the long term remains to be seen.

THANK YOU

Open access can be an advantage and at the same time a disadvantage for the journal; Advantage in the scientific side such as the readability of the journal and citations (a high citation number implies a high impact factor), and disadvantage in the financial side (there is not a main financial source for the journal).

and vice versa for the subscription journals.

A few obvious advantages of open access journals include the free access to scientific papers regardless of affiliation with a subscribing library, lower costs for research in academia and industry, in addition to improved access for the general public and higher citation rates for the author. However, a recent study concluded that overall citation rates for a time period of 2 years (2010/11) were 30% higher for subscription journals. After controlling for discipline, age of the journal and the location of the publisher, the differences largely disappeared in most subcategories except for journals that had been launched prior to 1996.

The main argument against open access journals is the possible damage to the peer review system, diminishing the overall quality of scientific journal publishing. For example in 2009, a hoax paper generated by a computer program was accepted for publication by a major publisher under the author-pays-for-publication model.Many newer open-access journals also lack the reputation of their subscription counterparts, which have been in business for decades. This effect has been diminishing though since 2001, reflecting the emergence of high quality professional open-access publishers such as PLoS and BioMedCentral.

Many opponents of the open-access model continue to assert that the pay-for-access model is necessary to ensure that the publishers are adequately compensated for their work. Scholarly journal publishers that support pay-for-access claim that the “gatekeeper” role they play, maintaining a scholarly reputation, arranging for peer review, and editing and indexing articles, require economic resources that are not supplied under an open-access model. Opponents claim that open access is not necessary to ensure fair access for developing nations; differential pricing, or financial aid from developed countries or institutions can make access to proprietary journals affordable. Some critics also point out the lack of funding for author fees.
