I have read that Cross-loadings of below .3 are often ignored! Can I have some reliable references to back this up please?
I have read exisiting work and authors tend to make this decision without supporting their decision!

Loadings lower than this are often considered unreliable or unimportant. The extent to which model fit is affected by constraining such loadings to $0.00$ can be explored using confirmatory factor analysis (CFA). I wouldn't call this approach "ignoring" them but maybe you had a different approach in mind. If so, please clarify in the question.
Edit: In the comments below, I provide some possible citations. Since you seem to want a more empirical treatment of this issue, I recommend Peterson (2000).
