			"""
			This is the Open Access Check Tool (OACT).
			The publication of scientific articles as Open Access (OA), usually in the variants "Green OA" and "Gold OA", allows free access to scientific research results and their largely unhindered dissemination. Often, however, the multitude of available publication conditions makes the decision in favor of a particular journal difficult: requirements of the funding agencies and publication guidelines of the universities and colleges must be carefully compared with the offers of the publishing houses, and separately concluded publication agreements can also offer additional benefits. The "OA Compliance Check Tool" provides a comprehensive overview of the possible publication conditions for a large number of journals, especially for the Swiss university landscape, and thus supports the decision-making process.
