As Google has worked to overtake the internet, its search algorithm has not just gotten worse.  It has been designed to prioritize advertisers and popular pages often times excluding pages and content that better matches your search terms 

As a writer in need of information for my stories, I find this unacceptable.  As a proponent of availability of information so the populace can actually educate itself, it is unforgivable.

Below is a concise list of useful research sites compiled by Edward Clark over on Facebook. I was familiar with some, but not all of these.

Google is so powerful that it “hides” other search systems from us. We just don’t know the existence of most of them. Meanwhile, there are still a huge number of excellent searchers in the world who specialize in books, science, other smart information. Keep a list of sites you never heard of.

www.refseek.com - Academic Resource Search. More than a billion sources: encyclopedia, monographies, magazines.

www.worldcat.org - a search for the contents of 20 thousand worldwide libraries. Find out where lies the nearest rare book you need.

https://link.springer.com - access to more than 10 million scientific documents: books, articles, research protocols.

www.bioline.org.br is a library of scientific bioscience journals published in developing countries.

http://repec.org - volunteers from 102 countries have collected almost 4 million publications on economics and related science.

www.science.gov is an American state search engine on 2200+ scientific sites. More than 200 million articles are indexed.

www.pdfdrive.com is the largest website for free download of books in PDF format. Claiming over 225 million names.

connectedpapers

the basic rundown is: you use the search bar to enter a topic, scientific paper name or DOI. the website then offers you a list of papers on the topic, and you choose the one you're looking for/most relevant one. from here, it makes a tree diagram of related papers that are clustered based on topic relatability and colour-coded by time they were produced!

for example: here i search "human B12"

i go ahead and choose the first paper, meaning my graph will be based around it and start from the topics of "b12 levels" and "fraility syndrome"

here is the graph output! you can scroll through all the papers included on the left, and clicking on each one shows you it's position on the chart + will pull up details on the paper on the right hand column (title, authors, citations, abstract/summary and links where the paper can be found)
