Policies and principles

The Open Access principles of University of Helsinki

The University of Helsinki requires researchers affiliated with the University to self-archive their scientific articles after they have been published in academic publications in the University’s Open Access repository HELDA. This can be done via the research information system TUHAT.

Self-archiving principles of University apply to all scientific scholarly articles. Publishers' policy and embargos to open self-archiving should be checked and actions taken accordingly. Library service deposit is also available.

Also Master´s and licentiate´s dissertations as well as Doctoral dissertations should be published openly. The theses submitted at the University of Helsinki are published in HELDA repository, instructions.

Several research funding providers require research results to be published in accordance with open access principles. You can consult the Sherpa/Juliet service to see your funder’s policy on Open Access publishing.


Funders´ requirements
Academy of Finland requires from the beginning of the year 2016 that Academy-funded projects are committed to open access publishing. Academy also requires projects to make their research data and methods freely available. The application of funding must include, as part of the research plan, both a publication plan and a data management plan. You can get more detailed information of the DMP from our Research Data Management -guide.
European Comission emphasizes public access to publicly-funded research results. Research projects operating under the programme of  Horizon 2020 are recommended to act openly. See also: European Commission background note on open access to publications and data in Horizon 2020. In Finland the programme is cordinated by  Tekes.
CERN requires commiting to open access publishing for all projects funded by CERN. Recommended oa-platform is  SCOAP3.
National Institutes of Health requires all peer-reviewed arcticles of NIH-funded projects to be published within 12 months in PubMed Central.

Gold Open Access: publication is immediately provided in oa mode through a high-quality open access publication.The publisher of the oa journal may charge an open access fee (article processing charge).

Hybrid open access: Research articles can be made openly accessible in a journal by paying an extra fee. Journal´s other articles still remain behind a paywall.

Article processing charge (APC) and Book processing charge (BPC) are payments charged by the OA publisher from the author or her/his institution to cover various publishing costs. Both Gold and Hybrid OA based journals can charge APCs.

Embargo: A period of time defined by the publisher,  during which the author has no permission to self-archive. Calculated from the publishing date of the original publication.

Double dipping: Institutions (libraries, universities) often have to pay twice for the same content when publishing in hybrid Open Access Journals.

♦ The scientific level of journals can be assessed for instance through Impact factors and through Publication Forum rating.

Impact factors: The journal impact factors are updated annually and can be found from the Clarivate Analytics Journal Citation Reports database. Most of the OA-journals have also an impact factor. You can get more information about impact factors and evaluation in general from Metrics Guide.

The Publication Forum – The classifications of scientific publication channels maintained by the Federation of Finnish Learned Societies.

JuFo Search Form - Search journals, conferences and publishers. The search can be targeted at specific fields of research.
