When a NetGalley member views the title record of a book listed by a PR or media agency, the PR/media agency's name will not appear--the publisher name and imprint in the title record will be the actual publisher of that title.
On the Browse Publishers page, titles represented by a PR or media agency will be listed under the PR/media agency's name.
There will not be a listing on the Browse Publishers page for individual publishers represented on NetGalley by PR/media agencies.
Please keep in mind that Browse Recently Added and browsing by Category are far more heavily trafficked pages than Browse Publishers.
