Are there any books recommended for in depth JIRA Admin knowledge

[Ilze Schoeman]

I have been a JIRA admin for a few years now and i'm looking to expand my knowledge of the software. However, most online learning sites only have the admin basics, which I am already familiar with. 

I am looking for potentially some online courses or books which could provide me with some more in depth knowledge of the admin features, and how to use them. 

I'm also very interested in being an expert at JIRA reporting so any books specific to this would also be great. 

Looking for Atlassian approved learning.

the easiest way to be an expert is by reading and responding to community post. there are wealth of real life scenarios the you may not encounter during regular business.

Couple of books that I refer to are:

1) "Jira Admin Workbook" - @Rachel Wright   (https://www.jirastrategy.com/)

2)Jira Administration - @Ravi Sagar (https://www.ravisagar.in/products)

Also you can also listen to Adaptavist pod cast as they have present a good information about atlassianchanges that can impact an admin : https://www.adaptavist.com/podcast/
