## What is Open Access?
In science, Open Access is defined as making scientific publications resulting from publicly-funded research available for use by researchers, students, businesses and society at large without financial, technological or legal barriers.
**Free Open Access** is "free and open access - the distribution of a work or the subject matter of a related right in a way allowing every person to have access to it in a place and at a time of his/her own choosing, and the possibility of free and technically unrestricted use thereof in accordance with the relevant regulations on the fair use or other exceptions provided by law".
"It is understood as free access to content that can only be read or used for permitted private use".
**Libre Open Access** is "free and open access - the distribution of a work or the subject matter of a related right in a way allowing every person to have access to it in a place and at a time of his/her own choosing, together with the granting of a licence for free, unrestricted and non-exclusive use of the work or the subject matter of the related right and any derivative works thereof; the licence may contain provisions imposing obligations on the user which do not affect the essence of the right of free, unrestricted and non-exclusive use, such as the obligation to provide the recipient with information relating to the author, producer or publisher, the subject matter of the licence and the provisions thereof, or the obligation to make the subject matter of the licence or any derivative works thereof available to the recipient under the same licence".
"It is understood as free access to content with the rights to reuse such content (modify or use it for commercial purposes), provided under Creative Commons licences".

## Creative Commons Licences
Open science and all activities carried out in this area require some regulations. The waiver of certain rights in works by their authors enable recipients to use them creatively and more freely.
Creative Commons licences are a set of ready-to-use legal tools dedicated to both authors and recipients. Their aim is to remove legal barriers that limit access to all kinds of scientific content. The author is responsible for determining the terms and conditions under which he/she makes his/her works available - the restrictions and freedoms that are imposed on the recipients of the content created by this author.
**The author using a Creative Commons licence always retains copyright**. The author allows others to copy and distribute the content he/she created, specifies whether such content can only be used for non-commercial purposes or limits the possibility of creating derivative works. The licensee must always comply with the terms and conditions of the licence, otherwise, the licence automatically becomes null and void. This means that information concerning the author and his/her rights must be correctly stated on each copy of the work.
In accordance with the concept of open science, in order to promote research and disseminate the scientific achievements of the employees of the University of Life Sciences in Lublin, we recommend depositing materials using the CC BY and CC BY-SA licences, where it is legally possible.

## Publisher policy
Before making material available in a repository, you should pay attention to the terms of your contract with the publisher. Some publishers automatically agree to make a work available as part of their publishing policy. Some publishers allow works to be deposited in repositories, but not always in their final form; sometimes these are preprints, author's versions, before final publication.
**Publishing policies of journals and publishers can be checked in the [Sherpa Romeo](https://v2.sherpa.ac.uk/romeo/) i [Most Wiedzy](https://mostwiedzy.pl/pl/magazine/catalog) databases**
The Sherpa Romeo is a tool that allows you to check publishers' policies towards open access and self-archiving of scientific papers by their authors in open archives and repositories. The service distinguishes between three types of documents: documents before the review process (submitted version), documents after the review process (accepted version) and documents already published (published version).
**[Glossary of useful terms](https://v2.sherpa.ac.uk/romeo/about.html)**
If a publisher does not have a policy on archiving papers in a repository, it is advisable to ask them directly for permission to make their work available in the repository.
