Very good read on Exploratory Factor Analysis

am battling “zombies” these days and comes the time that i need to use factor analysis for analysis. however, there are so many questions for a newbie like me, came across a few readings but nothing as useful as this which Dr Chai CS has shared:
Costello, Anna B. & Jason Osborne (2005). Best practices in exploratory factor analysis: four recommendations for getting the most from your analysis. Practical Assessment Research & Evaluation, 10(7). Available online: http://pareonline.net/getvn.asp?v=10&n=7
if you are exploring the use of factor analysis and you have qns like which extraction methods to choose, no. of factors to retain, sample size etc, just grab this article and you’ll be on the way to a good start. Thank you 蔡老师 (:
