OPEN LIBRARY: www.openlibrary.com

The ultimate goal of the Open Library is to make all the published works of humankind available to everyone in the world. While large in scope and ambition, this goal is within our grasp. Achieving it will require the participation of librarians, authors, government officials and technologists.

PDF DRIVE: www.pdfdrive.com

PDF Drive is a free search engine which allows you to search, preview and download millions of PDF files into your devices. Our crawlers are constantly scanning the world wide web to add PDF files to our database. In the case that PDF files are withdrawn from the web, then they are also immediately withdrawn from PDF Drive search results. In this way, our PDF Drive library stays up-to-date, while continuously growing and offering you an enormous database to search.
