My advisor recommended PERRLA as a help, but wants us to know APA format. As a returning student 18 years after getting my BSN, APA format in no way resembles what it was back in the day! ;o) Learning how to cite online references was an eye-opening experience with my APA book open in my lap and an example-paper provided by my instructor. Using PERRLA was like having a workbook where I could self-check and besides, it's not a cure-all, there are little quirks and problems I have to hand correct. The biggest advantage I've found to using PERRLA is that is stores your references--several times I've needed to re-use a resource and it was a snap and my little organized heart sings with joy when things are where they're supposed to be. Obviously, if your school bans its use, then by all means--don't use it--but I found it to be the bridge from impossible (dinosaur APA education, remember) to do-able.
