Not only do the very long, detailed, time consuming searches across many many databases. They are essentially creating the methods (and writing them) for the papers. Some librarians are also managing the database of retrieved citations (which are often in the thousands) in EndNote, RefWorks or other management systems as the researchers sift through and evaluate them.
So it is neat to see a list (provided by librarians on the library listserv) of the names of libraries and institutions that have librarians as co-authors in these type of papers.
Here they are: (If I missed anyone please let me know)
