My advisor asked me to use the book chapter (still not published, but will be published soon I guess) that we wrote with 4 other people. I am not the first author although me and 1st author made the same amount of contribution.
My question is that if it is ok to put it as a chapter of my PhD thesis? I find it weird since my advisor asked me to put it as part of my dissertation. Is it ok in terms of academic reputation because I am 2nd author of the chapter, although I made same amount of contribution as 1st author.
In other words, if I was 1st author would it be ok as well?
