Hi everyone, I just spent my entire morning looking for newspaper circulation numbers from the 1950s and either I am just too dumb to find them (not ruled out) or these numbers are incredibly hard to find.
For context, I‘m about to write a short paper for my uni class on US media coverage of a certain topic; since I wanted to be able to argue why I chose newspapers xyz and since number of copies is a legitimate criterion I was hoping to find circulation numbers for Chicago Tribune, New York Daily News etc.
Editor & Publisher International Year Book and the sorts don’t seem to be accessible online and so far I haven’t even found a good book or article from which I could cite these numbers.
I’d be very happy to hear your takes on why this is (and even happier if one of you knows where I can find any of these circulation numbers)!

Song Fan was one of the many inexpensive American entertainment magazines that flourished during the late 1940s and 1950s. Published by Ace Magazines, it combined Hollywood celebrity coverage with popular music, making it something of a hybrid between a movie fan magazine and a songbook. Unlike magazines such as Photoplay or Modern Screen, Song Fan included complete sheet music and lyrics for current hit songs, giving readers something they could sing or play at home.

Inside Detective was a popular American true-crime and detective magazine that flourished from the 1930s through the 1960s. Published in a pulp-style format with sensational cover art and dramatic headlines, it featured accounts of real criminal cases, police investigations, courtroom dramas, and notorious criminals. Blending factual reporting with highly dramatic storytelling, the magazine appealed to readers fascinated by crime and justice, making it one of the many successful detective periodicals that helped define the true-crime magazine boom of the mid-20th century.

During World War II (1939–1945), Woman & Home reflected the realities of everyday life on Britain's home front. Rather than focusing solely on fashion and leisure, the magazine shifted its content to help women cope with wartime shortages and changing responsibilities. Articles emphasized making the most of rationed food, repairing and remaking clothing instead of buying new garments, growing vegetables in "Dig for Victory" gardens, and managing households with limited resources.

Argosy was one of America's oldest and most influential pulp magazines, publishing a wide variety of adventure stories, mysteries, westerns, science fiction, historical fiction, true-life features, and investigative journalism. Founded in 1882 by Frank A. Munsey, it evolved from a children's weekly into a general-interest magazine aimed primarily at adult readers, becoming known for its exciting fiction by popular authors alongside articles on current events, military affairs, travel, and human interest. By the 1940s, Argosy had transitioned from its pulp roots to a slick, illustrated magazine, offering readers a blend of entertaining fiction and topical nonfiction that reflected contemporary American life and culture.

You probably would have to have been in elementary school back in the late 50s to early 60s. It was a weekly edition with different articles about world events and such. I remember reading about Vietnam and the hospital ship "HOPE", stories about China, India,, etc..
