Dear all, I returned yesterday from the annual Wikimedia Conference in Berlin. I've quite a few things to tell you about the conf and the strategy, but let me start with this: thanks to Leon Ziemba and Sam Walton, we have a nice way to show book-based statistics, meaning the aggregated pageviews for an entire book (main namespace + all the subpages).
Here's the important diff: https://it.wikisource.org/w/index.php?title=MediaWiki%3AHistlegend&type=...
So, as an admin, go into your Mediawiki:Histlegend page, and add this code
{{#ifeq:{{NAMESPACENUMBER}}|0|'''·''' [ https://tools.wmflabs.org/massviews?project=%7B%7BSERVERNAME%7D%7D&sourc... book pageviews counter]}}
Then, go into the History of a random ns0 book: you should see a new link "book pageviews counter" (translate as you wish).
I hope this tool is useful!
