@OddMinus1 @RustyBertrand academia.edu and researchgate.net are good places to look. Also, if you look up the university that the author is based at, many have 'institutional repositories' where the author is expected to put a 'pre-publication' version of their paper - but that often comes with limits (e.g. not available for the first 12months). Best option for brand new research is to email the authors.
