DAR Patriot Index

Good morning!
Yesterday, a co-worker asked me where the library's  DAR Patriot Index was. It was still listed in the catalog and a member was asking for it. The co-worker, being very efficient, had already checked all the possible and improbable places looking for it. I remembered the set but couldn't remember where it was until later.

I had discarded it (and somehow not removed it from the catalog) because of various postings like this one: http://scvgs.org/2012/07/07/dar-patriot-index-now-online/ that said that all the records were now online at the DAR web site: www.dar.org and that the old printed indexes were inaccurate and had soldiers listed whose service had been disproved.

This information was relayed to our member who replied that she has had trouble with the online index not listing ancestors for whom she has proved Revolutionary War Service.

Has anyone else had problem with the online DAR Patriot Index? Should printed indexes be retained when they have been superseded by online indexes?
