How to know a RNA-seq is polyA or total-RNA-seq in GEO?

Does GEO require that kind of meta data during submission?

Thanks,
As a rule of thumb, if a project doesn't explicitly mention looking at total RNA then the odds are high that it's polyA selected. When in doubt, you can always align against rRNA, since the alignment rate for polyA selected samples will be very low (<<1%), while rRNA-depleted (aka "total RNA") will have >1% rRNA (sometimes up to ~30%).
