I paid more than $100 for this reprinted book many years ago. Today I found the same book online. The cost is ZERO. I can download the entire book to my hard drive or to a jump drive or save it to an online storage service. I can print one page, multiple pages, or even the entire book. Even better, I can electronically search the entire book within seconds for any word or phrase. Not only can I search for names, but I can also search for towns, dates, occupations, or any other words of interest. Try doing that with a printed book!
The Internet Archive, also known as "The Wayback Machine," is a 501(c)(3) non-profit that was founded to build an Internet library. Its purposes include offering permanent access for researchers, historians, scholars, people with disabilities, and the general public to historical collections that exist in digital format.
The Internet Archive is best known for storing terabytes of old web pages. However, the organization has also expanded its role to digitize and store all sorts of public domain material, including old books, movies, audio recordings, radio shows, and more. I have also found a few modern books on The Internet Archive that were legally contributed by the copyright holders themselves.
The site's Text Archive contains a wide range of fiction, popular books, children's books, historical texts and academic books. The list includes genealogy books as well. The Internet Archive is working with several sponsoring libraries to digitize the contents of their holdings. The Allen County Library in Fort Wayne, Indiana is one library that has contributed many digitized genealogy books to The Internet Archive as is the Harold B. Lee Library at Brigham Young University. In addition, private individuals are invited to scan the public domain books in their personal libraries and upload them as well. (See http://www.archive.org/about/faqs.php#195 for information about contributing your books.)
The result is a huge resource of books in TXT, PDF, and other formats, books that you can download to your computer, save, and then search for every word. The same books are also visible to Google and other search engines, including online every-word searches. The TXT files have lost the formatting of the original books: there is no bold or italics or underlining, as such formatting is not supported by TXT formatting. In addition, paragraph indentations and other "spacing" often is lost.
Many of the books available were converted to TXT format by OCR software. OCR never converts all words perfectly so you can expect to find numerous OCR errors in these documents. For instance, The Harmon Genealogy, comprising all branches in New England has some words mis-scanned and many dates have errors in them. The common one was substituting the letter "I" in place of the number one, such as "I920" instead of "1920." That will cause difficulty if you are electronically searching for specific words or numbers.
Of course, the Internet Archive is not the only source of digitized books. In fact, Google Books is a much better-known source of digitized books. Operated by a well-funded commercial company, Google Books gets most of the publicity and has probably digitized more books. However, with commercial ownership comes proprietary business methods. Google Books generally are available for download only in PDF format. Once stored on your computer's hard drive or jump drive, those books are not easily searched, although there are some technically-advanced methods available to add search capabilities.
In contrast, books stored on The Internet Archive are already searchable for any word or phrase, both when online and after being downloaded. Many of the books are available in TXT format (easily searched) while others are in PDF format. Even the PDF files that I downloaded were all immediately searchable with no conversion required. I am not sure if all the PDF files are searchable, but the ones that I tried were immediately searchable.
The Internet Archive also provides most books in http, EPUB, Kindle, Daisy, and DjVu formats in addition to TXT and PDF. As a result, the books and other documents can be read on almost any ebook reader as well as on computers, iPads, and most cell phones that have web browsers.
The Internet Archive does not yet have all the genealogy books ever published. In fact, nobody seems to know how many genealogy books are available this way. Even the folks at The Internet Archive don't know. They simply scan everything they can find and don't worry much about classifying the topics.
I searched the "Texts" section of The Internet Archive for the word "genealogy" and found 34,539 "hits." By searching in "Texts," I was able to ignore the "hits" found on the Internet and in other sources. That's not a definitive answer as the word "genealogy" obviously will exist more than once in most books. However, it does provide a rough idea of the popularity of the word in The Internet Archives' books, magazines, and other texts. Whatever the true number, there must be thousands of genealogy books available today on The Internet Archive, and the number is growing rapidly.
The Internet Archive also has scanned and digitized the U.S. Census records from 1790 through 1930. Unlike the commercial providers of census data, the versions provided by The Internet Archive have not been indexed. They are useful only if you already know where to look for your ancestors. Small towns can easily be searched one page at a time while cities probably are best searched if you already know the Enumeration Districts involved.
Also unlike the commercial providers of census data, the census information on The Internet Archive is available free of charge to everyone.
In fact, everything on The Internet Archive is free. The site doesn't have a method of accepting credit cards. As a non-profit, however, the organization does accept donations which are tax-free to Americans.
In a casual search, I found all sorts of material of interest to genealogists on The Internet Archive, including these:
Compiled service records of soldiers who served in the American Army during the Revolutionary warThe above is only a tiny fraction of the many books available free of charge on The Internet Archive.

The Internet Archive isn't perfect, but it does provide a great resource for genealogists, historians, and others. If you are looking for information about your family tree, I'd suggest that you check out The Internet Archive at http://www.archive.org
If you are interested in The Harmon Genealogy, comprising all branches in New England, go to http://www.archive.org/stream/harmongenealogyc00harm/harmongenealogyc00harm_djvu.txt. Caution: This book is great; but, like most genealogy books, does contain a few errors. Author Artemas C. Harmon did a very good job of research, but his work was not perfect.
