[watermark]科学信息搜索引擎Scirus (期刊文章、网页) http://www.scirus.com/ Main features: Focuses only on web sites containing scientific content - quickly pinpointing key data by targeting sites that conventional search engines cannot find, such as university Web sites and author homepages. Searches both free and journal sources - saving you time by covering over 135 million science-related pages, consisting of 120 million Web pages, as well as 17 million records from sources such as ScienceDirect, MEDLINE on BioMedNet, Beilstein on ChemWeb, BioMed Central, US Patent Office, E-Print ArXiv, Chemistry Preprint Server, Computer Science Preprint Server, Mathematics Preprint Server, CogPrints and NASA. Locates peer-reviewed articles - ensuring you do not miss out on this critical information source by finding more peer-reviewed articles than any other search engine. Delves deep into Web sites - revealing valuable information by digging far deeper than most search engine 'spiders' or 'crawlers' and indexing complete documents. Reads non-text files - allowing you to locate vital PDF and PostScript files that so often are invisible to other search engines.[/watermark] |
