摘要	Open access (OA) publishing removes subscription paywalls, making research freely available to all readers online without subscription fees. The Budapest Open Access Initiative (2002) defined OA as the right to read, download, copy, distribute, print, search, and link research freely. Multiple OA models exist: Gold OA (immediate free access, often author-funded via APCs), Green OA (free self-archiving in repositories), and Diamond OA (free to both authors and readers). OA expands research impact, enables global participation in science, and aligns with public funding mandates. However, OA models vary in sustainability and are sometimes exploited by predatory publishers.	Predatory journals are fake academic publishers that exploit the open-access model by charging authors publication fees without providing peer review, editorial oversight, or quality control. Coined by librarian Jeffrey Beall in 2010, the term describes publishers that prioritize profit over scientific integrity, accepting nearly all submissions (regardless of quality), using deceptive marketing (claiming high impact factors, faking indexing, using names similar to established journals), and often hosting work that would not survive peer review. Publishing in predatory journals damages an author's credibility and wastes research dissemination efforts.
