Microsoft have been generously offering free eBooks for quite some time (since 2006 as far as I can see) on a wide range of topics and technologies. This includes SQL Server 2012, 2014 and 2016, and relevant topics like Power BI, Machine Learning, Azure, Windows Server 2012 R2 (with it’s support for Dynamic Quorum & Dynamic Witness), Windows Server 2016, SCOM, SCCM, Hyper-V and much more.
So do yourself a favour, grab one of the eBooks, put your feet up and have a read. We should never stop learning.
