Chapter One

The Dewey Decimal system does not fit genealogical research. Mr. Dewey must not have been a genealogist. He didn't code his book keeping inventory system based on a genealogist's needs but on a book keeper's or librarian's needs. It is similar to the difference between a book-keeper and an investor. The book-keeper tells you where the money is, the financial advisor tells you where to put it. A book keeper or librarian tells you where the book is, not how you should be interpreting it.

I remember when I went to the Chicago Historical Library because my mother's family had settled there back in 1860. When I told the librarian my purpose, he tried to send me to the Newberry Genealogical Library. No, I wanted Chicago sources. When I told him I wanted to look at a Chicago Fire Department Report that dated earlier than 1871, I had looked at it before, he told me everything had been burned in the Chicago Fire of 1871. Yes everything in Chicago burned, but not everything about Chicago burned if it was located outside of Chicago at the time of the fire. Finally I just asked the page. He knew.

Genealogy is a special skilled researching hobby that is foreign to the average librarian and many historians. The librarian must be able to work in any and all departments. They aren't paid for or interested in genealogy that you should know how to do yourself so you need to learn how to use what they know. And they know the Dewey Decimal system. They went to school to learn it, the WHOLE system. But relax, you only need to learn a little.

Ironically, the genealogist needs to know his family's location, location, location. The librarian needs to know the book's location. But the book's location is not necessarily on the shelf based on where your family lived. It's not even based on where Mr. Dewey lived.

Dewey based his system on three identifiers: Title Author Subject

He did not base it on location. He did not base it on Kent County. The cemeteries of Kent County are shelved together. All histories of Kent County are shelved together. But cemeteries and histories of Kent County are on different shelves. The cemeteries in Kent County and the histories of Kent County are not shelved together as they are different Subjects. A genealogist is interested in all information available about, in, around, near, within Kent County and is frustrated when they are not all shelved together. A genealogist doesn't care about subject, he cares about place first and then all the people who passed through that place during a certain time.

I originally wrote this essay about 15 years ago and have just re-entered the arena only to discover the proliferation of indexes. And that is the beauty of Dewey. It is flexible. But the old books remain on the shelf, numbered the old way. The new books are numbered the new way. Confusion. So a call number is not permanent to a particular book over the years and it is not identical in every library. But we non-librarians don't need to know cumbersome technicalities.

I have tried to break down the theory, so you can understand the overall numbering system but you need to understand there are many exceptions.

The 929 starting portion of the call number means genealogy. In my day the only books under 929 were how-to books, heraldry, royalty. Common man wasn't included. And that has changed. Now common man has risen and taken over 929 causing the retirement of some of the old numbers and the creation of new. I used to just ignore 929 and concentrated on other subjects that contained, non-indexed, information relative to a family or place.

So compilations useful to a genealogist were shelved by subject, any subject other than genealogy, and then by geographic location but not in alphabetical order but by region. Cemeteries were shelved in one place. Census records in another. Dewey just didn't seem to work. A genealogist had to run all over to find information. The meat was in other subject areas. If you wanted any information on someone who lived in Kent County, you had to look in the Social Sciences or History sections thus making history's and geography's connection to genealogy very apparent. .

Prepared for a lecture given on February 14, 1981

by Barbara Vander Mark, Chairman, Library Services Committee

and Martha Seaman, Head of Technical Services, Grand Rapids Public Library

Mr. Melvil Dewey dreamed up this numbering system in 1876. He arranged all human knowledge into 10 categories with many subdivisions according to his nineteenth century American egocentric view of the world. Prior to this, books were described by physical location (a certain shelf on a certain wall). Unfortunately, it caused problems as library collections grew and changes were made in the buildings. Dewey's numbering system allowed each library to adapt his system for its own use. Therefore, the same book will have a different call number in different libraries.

By using classification numbers, books with similar treatments of the same subject should be shelved together. The books are first divided by broad disciplines, and then sub-divided again and again into more specialized treatments of a subject.

To the non-librarian, alll books on one subject are NOT classified together. For instance, if the subject is children, all books about children are NOT shelved together. Instead books about art for children are classified under Art, ethics on raising children are classified under Ethics, etiquette for children under Etiquette, hygiene for children under Hygiene, psychology of children under Psychology, etc.

Does this look like gibberish to you? Greek maybe? This number, referred to as a Call Number, can mean the difference between finding the information you seek or being stuck on yet another Dead End. Those call numbers, actually have a simple meaning. They are a code. You have to write down the whole number. Just like the old telephone exchanges meant something. Cherry was the exchange in the southeastern portion of the city. Glendale was the central city. Empire the northeast. The first few numbers told you where the person lived, but you still had to dial the whole number. You couldn't just drop off the last five numbers. Just dialing the exchange didn't get you the person you wanted. And just knowing the Dewey Classification numbers won't get you the specific book either.

1976 Date of publication

Books are arranged on the shelf in numeric order.

929.12 is shelved before 929.3. It is read 12/100 before 30/100 NOT 3 before 12.

Cutter Number - The first letter represents the first letter of the author's name. The numbers represent the rest of the author's name and are chosen according to a special code. The last letter represents the first letter in the title. The Cutter number is arranged in Alphabetical Order, and then in number order. The number is a decimal.

A42 is shelved before B3 or A before B

H372 is shelved before H38 or 372/1000 before 380/1000

H382 is shelved before H40 or 382/1000 before 400/1000

R42a is shelved before R42b or a before b.
