About Text Quality

The vast majority of books available on Bookshare.org originated as scanned files, and these submissions inevitably contain errors caused by scanning equipment and character recognition software. Bookshare.org is committed to making as many books accessible as possible while still maintaining standards for text quality and readability.

Bookshare.org is also committed to helping its readers make informed choices about the books they choose to download. For this reason, individuals submitting books to Bookshare.org are asked to include an assessment of text quality (Excellent, Good, or Fair). Submissions are then analyzed using a software tool that checks words against a dictionary and delivers its own rating. As a third quality assessment measure, Bookshare.org volunteers check the actual book and verify the validity of the combined rating.

Downloading a Book: What to Expect

Every book available for download has been assigned a Quality rating: Excellent, Good, or Fair. Submitted books determined to be of less than Fair quality by the submitter, the Bookshare.org quality assessment tool or the volunteer are not published.

Bookshare.org's quality assessment tool uses the following metrics for each quality level:

• Excellent, almost no errors: 99.85% character recognition accuracy or better
• Good, some errors: 99.72-99.85% character recognition accuracy
• Fair, many errors but legible throughout: 99.00-99.72% character recognition accuracy

Submitting a Book

Please submit your scanned book, even if you are unsure if the text quality is acceptable. A Bookshare.org volunteer or the automated quality assessment software will identify unacceptable books and ensure that they are not published. By submitting your book you allow Bookshare.org's volunteers (and OCR correction software) the chance to improve and make the book available to the community.

When submitting your book, please estimate the quality of the text as Excellent, Good, or Fair.

Following are text passages representative of each rating:

Excellent (almost no errors)

Geniuses, the mathematician Paul Halmos wrote, "are of two kinds: the ones who are just like all of us, but very much more so, and the ones who, apparently, have an extra human spark. We can all run, and some of us can run the mile in less than 4 minutes; but there is nothing that most of us can do that compares with the creation of the Great G-minor Fugue." 4 Nash's genius was of that mysterious variety more often associated with music and art than with the oldest of all sciences. It wasn't merely that his mind worked faster, that his memory was more retentive, or that his power of concentration was greater. The flashes of intuition were nonrational. Like other great mathematical intuitionists -Georg Friedrich Bernhard Riemann, Jules Henri Poincar6, Srinivasa Ramanujan -Nash saw the vision first, constructing the laborious proofs long afterward.

Good (some errors)

The OFF Plan is not a three-week meal plan to follow (you'll be happy to hear that there are no meal plans at all), or a liquid drink you consume every day for lunch, or a list of mandatory changes that each of you has to follow. These alternatives are not natural, lifestyle changes because you cannot practice them for the rest of your life. This is why many of the commercial weightloss programs have such low long-term success rates'at best only 5 to 10 percent keep the weight off. The OFF Plan has an 80 percent one-year success rate and a 62 percent five-year success rate. You are about ten times more likely to keep the vpeight off7rith the OFF Plan .

Fair (many errors, but legible throughout)

they moved a little hastily, for it was a good six miles back to London, and the red sun was already smlouetting the branches of the trees along the River Brent, two maes to the west. When they'd gone the old man turned around to watch the sun's slow descent. The Boat of Millions of Years, he thought; the boat of the dying sungod Ra, tacking down the western sky to the source of the dark river that runs through the underworld from west to east, through the twelve hours of the night, at the far eastern end of which the boat will tomorrow reappear, bearing a once' again youthful, newly reigoited sun.
