The first edition of Laurie and Kyle Klein's book, Infrared Photography: Artistic Techniques for Brilliant Images, came out in 2016 (and was featured here). Now there's a new edition from Amherst Media with extra input from technologist Shelley Vandegrift. I haven't as yet seen the new edition but I like the earlier books so this should be worth consideration.
Info on the book is on this web page.
Laurie and Shelley are also giving a three day "Intensive" course towards the end of September. This will be held using the ubiquitous Zoom running from noon to 1700 (I assume east-coast USA time) and with a course fee of $695. It's aimed at photographers across a range of infrared experience. The middle day will be a practical, where you shoot around your own area with the opportunity for discussion. More info on Laurie's web site.
