Pubget [beta] is a free search engine for PDFs in the life sciences. It indexes nearly 20 million life science research documents, including those in PubMed®. Search it like you would PubMed or Google Scholar. The difference is that Pubget gets you the PDF right away, if Carnegie Mellon has a subscription. The core service is free to the scientific community. Pubget makes money by providing marketing (ads) and intranet services to the lab equipment, biotechnology, pharmaceutical, and other research industries and through premium services (coming soon).
