This series of small pamphlets contains a mix of fiction and non-fiction, published circa 1900. The series has no official title printed on the pamphlets, but each is numbered. Much (possibly all) of the content is identical to that found in the Multum in Parvo Library
produced starting in January 1894 by A. B. Courtney and other publishers, but the "Multum in Parvo" name is not found on these versions. The publisher of these editions is presumed to be John Regan
of Chicago based on advertising found within the pamphlets. In all likelihood, John Regan published the untitled and undated but numbered 5 Cent Pamphlets contained in this collection sometime between 1900 and 1917.
