The Library of Congress, as we previously discussed, maintains a web listing of the eighteen mostly commonly found reprinted newspapers . Most reprints which turn up today will be found in this list, however many others do exist.
Rick Brown, who maintains the “historybuff.com” website and who edited the journal “Collectible Newspapers” for many years, created a master list of some 567 reprinted newspapers. Should you encounter a newspapers and you are suspicious of its genuineness, check the list of titles and dates on “American Newspapers Known to Have Been Reprinted”  which can also be accessed from the home page of our website. If the title & date appear on this list your suspicions many be justified.
If you care to take an additional step towards determining genuineness, Rick offers a more detailed “Annotated Index of Newspapers Editions Known To Have Been Reprinted…”  for a modest charge, which offers additional details for each entry.
Although reprinted editions are exeedingly rare in the hobby of early newspapers—and most common reprints are easy for even a novice to spot—having access to such a list is of much value to the hobby and can provide some comfort when pursuing historic newspapers for one’s private collection.
