The moderators here would like to have links with quotes from
other sources. It is something they are asking for from all the
posters on other forums too, not just here on PN.

I always try to do that anyway, but sometimes I forget and don't include them for PubMed. The PubMed articles have a code number at the bottom which if typed in to PubMed's keyword field will bring up the article that way. It is an identification number. But many people don't know that.

The abstracts there are not the whole article, they are excerpts themselves.
