FicBooks
FicBooks是一个免费的搜索引擎,它允许你搜索并下载数百万的PDF文件到你的设备中。
FicBooks is a free search engine which allows you to search, 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 In the case that PDF files are withdrawn from the web, then they are also immediately withdrawn from FicBooks search results. In this way, our FicBooks library stays up-to-date, while continuously growing and offering you an enormous database to search.
