invisible web, hidden web, and deep web all refer to the same thing: a massive storehouse of online data that the search engines don't capture. That's because terabytes of information are buried in databases and other research resources. Searchable and accessible online but often ignored by conventional search engines, these resources exist by the thousands. Known in research circles as the invisible, deep, or hidden Web, this buried content is an estimated 500 times larger than the surface Web, which is estimated at over four billion pages. This mass of information represents a potent research resource, no matter what your discipline or interest. Below are some tools to help you mine it. Students and serious researchers may also find our collections of web directories and scholarly and academic research tools and strategies useful.
"Max Planck Digital Library
Digital information has become indispensable to the daily routine of every researcher, in fields from educational research to astrophysics, from coal research to chemical ecology. An article is downloaded every second, a new publication goes out every 10 minutes. Research data, delivered in highly organized form. It is MPDL's goal to enable and orchestrate this information flow for all Max Planck Society researchers."
DeepDyve is the largest online rental service for scientific, technical and medical research with over 30 million articles from thousands of authoritative journals. Today, people who research online must visit numerous websites to find the information that they seek. As they locate interesting titles or abstracts, they must often pay $30 or more to read the full-text of each article. DeepDyve makes research easy and affordable.

rclis is pronounced "reckless" and stands for research in computing, library and information science. rclis is a project to build a database about all current and current and past research in computing and library and information science. The data will be freely available for public and private, commercial and non-commercial purposes. It will serve as a testbed for digital library research. It will initially be released using the public metadata harvesting protocol of the Open Archives Initiative (OAI), using the Academic Metadata Format (AMF). Other delivery mechanisms and metadata formats may be added as time permits.
"The Alexandria Digital Research Library (ADRL) is UC Santa Barbara Library's home for collections of digital research materials, including images, text, streamed media, and numeric and spatial data. This comprehensive digital library, when complete, will provide access to millions of hidden digital research assets in UCSB Library's possession, and serve as a single search access point."
"Currently making 1.67TB of research data available.
Sharing data is hard. Emails have size limits, and setting up servers is too much work. We've designed a distributed system for sharing enormous datasets - for researchers, by researchers. The result is a scalable, secure, and fault-tolerant repository for data, with blazing fast download speeds."
"store, share, discover research - get more citations for all of the outputs of your academic research over 5000 citations of figshare content to date"
