Nine years ago and a few days, I was on the taxi to the airport from Internet Librarian 2004 and in chatting with the driver he said something like "have you heard Google is doing something for academics?".
I hadn't. It was Google Scholar.
So it seems appropriate that nine years ago to the day when I first created my blog and posted about the launch of Scholar, I'm writing about a new feature: Google Scholar Library.
Today we’re launching Scholar Library, your personal collection of articles in Scholar. You can save articles right from the search page, organize them by topic, and use the power of Scholar's full-text search to quickly find just the one you want - at any time and from anywhere. You decide what goes into your library and we’ll provide all the goodies that come with Scholar search results - up to date article links, citing articles, related articles, formatted citations, links to your university’s subscriptions, and more.
Google Scholar blog - Google Scholar Library - November 19, 2013
Basically it lets you save citations, and label them. Google Scholar results get a new "Save" button.
You can apply labels e.g. "Library Future"
and view your library by label
if you have a Google Scholar profile ("Google Scholar Citations") then you can get recommendations based on your citations
You also get automatic "My Citations" and "Cited by me" sections in the library.
