All google turns up easily are cloaked paywall sites and you have to do a lot of digging to find freely available versions of papers (e.g. pre-published), although that usually turns into an impractical task. Cloaked sites are against their terms of service, but not apparently if you’re big enough/pay them (elsevier and other scumbag leeches).

Perhaps what is most worrying is that it is simply impossible to find all such information without using a global search engine …
