Hi, I was under the impression that librarians and archivists were being encouraged to add links to their holdings when appropriate: see Editors who may have a conflict of interest: Subject and culture sector professionals and Advice for the cultural sector   As advised, I submitted a proposal to Wikipedia talk:WikiProject Physics Wikipedia talk:WikiProject Physics  Proposed Photo Links to add links to Emilio Segrè Visual Archives (ESVA) photo holdings and met with no resistance.  Perhaps it would be better submit the proposed change to each page individually, or maybe to just link to the ESVA homepage (and not search results)  or is there any reason not to link to ESVA at all?  Can you advise?
