Dear Brooke,

The database is also changing. In 2014, we published in JoI:


(articles + reviews + letters; integer counting)

This morning, I find:

This is integer counting, WoS Core collection; articles + reviews.
Indeed, China has overtaken the USA.

Best,
Loet

>Hello all,

>Earlier this year, the following Nature headline grabbed a lot of

>articles”. Speculation ramped up about factors driving global change in 
>research, how scientific communities in the West should respond, and so 
>forth.
>
>
>
>Along with these discussions were some questions about the approach to 
>measurement, what influence it might be having on the result, and how 
>we should interpret the finding. Specifically, people highlighted that 
>fractional rather than full counting was used.

>
>In this week’s blog post, we offer an accessible explanation of these 
>two methods, the differences between them, and what they mean:

>Over the coming weeks, we’ll explore the differences from a number of
