The document discusses open access publishing, which makes scholarly works freely available online without subscription fees. It notes that open access can increase visibility and impact of research. There are two main types of open access - gold, which is immediately available online, and green, which is available through repositories after an embargo period. While open access has benefits, challenges include improving research quality as some open access journals accept dubious works, and addressing high article processing charges. Tools are being developed to help identify predatory open access journals.
