The publisher icons in PubMed are not reliable. For the best PubMed experience, never click the publisher icons. Always use the Check TTUHSC icon, or the icons provided by LibKey Nomad (most reliable).
Technical details - Publisher icons are inserted into PubMed records at the discretion of the National Library of Medicine (NLM), not by the TTUHSC libraries.
