Those of you who are unfamiliar with Virkus’ The Abridged Compendium of American Genealogy (later The Compendium of American Genealogy) should know what it is and what it isn’t, what’s wrong with it, and if there are any redeeming qualities.
In short, you should know the truth about it, and far more importantly, what’s been done to it recently since it was published more than a half century ago.
This massive work in seven volumes, published over a decade and a half between the 1920’s and the 1940’s, maps out verbally an enormously large swath of generation-by-generation American family history over basically a three century period.
Despite the potential ancestral history value that promises, and the fact that it is the one genealogy resource that can be found in most libraries, conventional wisdom these days says that it should be avoided like the plague.
It has been known for a long time that it contains many errors, but I’ve never seen anyone quantify that statement. Is it 30% errors? 40%? 50%? The much lower answer may surprise you.
But what if the correct answer was that it contains 50% errors? That would mean that one out of every two statements or dates is wrong.
The glass-half-empty thinkers will say this massive genealogy resource is useless. The glass-half-full thinkers will say “Wow! Wouldn’t it be great if we knew which half of this massive genealogy resource is correct?”
Highly respected genealogist Donald Lines Jacobus said about it “because of the high proportion of known errors, conscientious genealogists do not use statements in this work without verification.”
“It is often a useful reference work for those who know how to use it properly” he went on to say.
Suppose a conscientious person with Mensa-level intelligence spent 15 years digitally indexing, in lineage-linked format, the Virkus collection along with hundreds of other books and periodicals, filtering out annoying and confusing duplication, error checking each entry against everything else that had been previously entered, and connecting them to each other wherever appropriate?
There’s no need to imagine the enormous upgrade in quality and usability that has already happened to Virkus’ massive work (as well as to hundreds of other books and periodicals, including many from NEHGS and NYGBR). Just explore for yourself in the National Treasure.
