The Library of Congress draws a neighbor set defined not by other government or archival institutions, but by a dense mix of politicians, journalists, news publishers, and civic organizations — all compressed into a narrow similarity band running from 0.94 down to 0.93.
The shape is flat: no single neighbor dominates. Smithsonian leads at 0.94, the only Education-subcategory entity in the top 10, followed immediately by Jon Ossoff (0.94) and Fair Fight (0.94) — a politician and an activism organization within a rounding error of the top spot. Tom Perez (0.94) and Stacey Abrams (0.94) continue the politician cluster, while Southern Poverty Law Center (0.94) and Tim Kaine (0.94) extend it further. PBS and C-SPAN (both 0.93) are the only TV Channels in the top 10, and The Associated Press (0.93) rounds out the set as a News Publisher. Tallying subcategories across the ten: four are Politicians, two are TV Channels, one is Education, one is Activism, one is Non-Profit, and one is a News Publisher. No other Government entity — the Library of Congress's own subcategory — appears in the top 10.
The cross-kind pattern here is the finding: an institution classified as Government draws its nearest audiences almost entirely from politicians, civic nonprofits, and public-interest media, with the Smithsonian as the lone institutional peer.
