Geometry book using Erlangen program

Maybe it's this pair of books, no.1 and no.2, by Vaughn Climenhaga (who seems to be from the University of Houston). They were authored in 2008 and 2009 resp. with Yakov Pesin.

Same author also just released another book (that seems to fit the description) with Anatole Katok called From Groups to Geometry and Back which is based on a course taught in 2009.


You may be referring to Geometry by Ivan Izmestiev. I could not find any place to buy it, but perhaps you can request an inter-library loan at your local library. Although it is a fairly recent book, so "long ago", may not fit, although it is in the same spirit, and should be a valuable resource.
