I am currently working on my second book and I want to make it open access this time. I know there is many way to put the book online (github, bookdown, etc.), but I am worried on how it will be perceived by colleagues to not have the book officially published by a publisher.
I am specifically refering to scientific book targeted primarily for scholars. My book is actually on how to use the R software in french, but the answer can have broader range.
Is it okay to put a book online without a publisher online?
How will it be perceived by other academics?
Should I be better to try to publish the book with a known publisher and pay the open access fee?
