An intentionally blank page is a page that is devoid of content, and may be unexpected. Such pages may serve purposes ranging from place-holding to space-filling and content separation. Sometimes, these pages carry a notice such as, "This page is intentionally left blank." Such notices typically appear in printed works, such as legal documents, manuals and exam papers, in which the reader might otherwise suspect that the blank pages are due to a printing error and where missing pages might have serious consequences. The phrase is a self-refuting meta-reference, in that it falsifies itself by its very existence on the page in question.

[edit] Uses for intentionally blank pages
[edit] Print media
Intentionally blank pages are usually the result of printing techniques. Book pages are often printed on large sheets because of technical and financial considerations. Thus, a group of eight, sixteen, or thirty-two consecutive pages will be printed on a single sheet in such a way that when the sheet is mechanically folded and cut, the pages will be in the correct order for binding. Such a group is called a section or signature. Books printed in this manner will always have as many pages as a multiple of the large sheets they were printed on, such as a multiple of eight, sixteen, or thirty-two. As a result, these books will usually have pages left blank.
For example, if a book with 318 pages of content is printed using 32-page signatures, it will require 10 signatures, 320 pages in total. At the very end of the book — that is, at the end of the last signature — there will be 2 unused (blank) pages.
If a printer's document processor has been designed to skip completely blank pages, notices may also be required on intentionally blank pages to prevent incorrect page numbering.
Intentionally blank pages are ubiquitous in technical and instructional manuals, directories, and other large, mass-produced volumes of text. The contents of manuals produced by a given product's vendor are often compiled from generic instructions suitable for a variety of products, with additional instructions or chapters included for the specific product or model in question. This automation of manual-generation leads to intentionally blank pages required to fit the requirements for mass printing.
In digital documents, pages are intentionally left blank so that the document can be printed correctly in double-sided format, rather than have new sections start on the backs of pages. Intentionally blank pages have also been used in documents distributed in ring binders. The intention is to leave room for expansion without breaking the document's page numbering. This allows updates to be made to a document while requiring minimal new pages, reducing printing costs. The only drawback is the increased time required by the reader to manually insert various newly updated pages into their correct locations in the document.
[edit] Standardized tests
Intentionally blank pages can be useful in standardized tests such as the GCSE, HSC, SAT, CAT, ACT, MCAT, and GRE. In these exams, there are often individual, timed sections in which test-takers are prohibited from proceeding to the next section until that section's time interval has passed and the examiner allows them to continue. Because all of these separate sections are printed consecutively in the examination booklet, it may be possible for a test-taker who has finished the section early to see through the page and read the problems in the next section. By placing intentionally blank pages between these sections, the test-taker is prevented from cheating in this way. By printing a notice on the page, such as "this page has been intentionally left blank", test-takers will not be concerned that their test has been misprinted.
[edit] Sheet music
In books of sheet music, pieces of relatively short music that can span two to four pages often need to be arranged so the number of page turns for the performer is minimized. For example, a three-page work (starting on the left hand sheet) followed immediately by a two-page work involves one page turn during each work. If a blank page immediately followed the three-page work (on the right hand sheet), the two-page work will span the left and right pages, alleviating the need for a page turn during the second work.
[edit] Variations
Intentionally blank pages placed at the end of books are often used to balance the folios which comprise the book (see bookbinding). Often these pages are completely blank with no such statement, or are used as "Notes" pages, serving a practical purpose. In the case of telephone number directories, these pages are often used to list important numbers and addresses. In novels, pages may list other books available from the same publisher.
Book publishers have also used stylized designs (dingbats) underneath the last paragraph of a chapter to indicate that no other content is to be expected until the next chapter, allowing for the possibility of blank pages without misunderstandings by the readers.
[edit] Examples
Author Idries Shah, distrusting critics' reviews of his books, wrote The Book of the Book (1969, ISBN 0-900860-12-X), which consists of sixteen written pages of reviews of itself. The rest of the book is intentionally filled with about 140 blank pages to give the appearance of a normal book. Initial reactions were generally negative, but over time critics have come to praise it.[who?]
A similar example to the intentionally blank page can be found in electric road warning signs, normally used to indicate traffic problems down the road. Rather than have the sign remain blank when not in use, some employ phrases such as "No Reported Problems" to reassure drivers that the sign is still functional (though in many jurisdictions current practice is to present some generalized traffic safety message such as "Drive Drunk: Go to Jail" when there is no specific information to present).
An example similar to both the intentionally blank page and the road signs is the self-diagnostics of most recent computer monitors. When no signal is detected, they will often display red, green, and blue bars and a message to the effect of "Check input signal, this monitor is working." This is to let the user know that the problem is not with the monitor.
The Andy Griffiths book "Just Stupid," begins with a cartoon snail saying to the reader, "This page would be blank if I were not here telling you that this page would be blank if I were not here telling you that..." on an endless loop.
