Folks, Over the years we have discovered that certain features in books are more difficult for scanners and their OCR software to render accurately. These are the basis of the categories of difficulty that we assign to books. For example it is rare to find a book as simple as Level 1 with text, page number, and no running headers on each page. At the other end of the spectrum it takes several months for an outsourcer, who can assign a team to a single textbook, to do a Level 5 or 6. Most often you find yourselves doing Levels 2 and 3 books. As a refresher course below I list the distinctions we make between different levels. Scott Rains Levels of Complexity for Scanning or Proofreading a Book Levels are assigned to all books, to determine their overall difficulty in proofing. 1 is the easiest type of book to proof, and 6 is the hardest. The time it takes to proof a book depends on its level and its length. Level 1: The book has only text, chapter numbers, and page numbers, in a standard font. Level 2: The book has running headers or footers, in a standard font, on at least half the pages. Level 3: The book has page numbers or running headers in a non-standard font, footnotes, superscripts, captions, charts, or more than a few words in a foreign language, poems, or pictures. Level 3.5: The book has pictures that need to be described. This is mostly used for childrens’ picture books. Level 4: The book has many words in a foreign language, many pictures, many charts, or insets. Level 5: The book has many areas of separate text on eachpage, formulas, text that forces scans with differing brightness (like different colors), or heavily formatted text. Level 6: The book has text in a non-standard font (which forces the book to be retyped), text at a non-horizontal angle, or massively formatted text.
