_{Soviet era housing districts (microdistricts) often have a complicated network of access lanes thought too small to merit their own names. Buildings in these lanes are ascribed to larger streets which may be quite far from their location; a building placed along a street may sometimes be ascribed to another street, which sometimes makes finding a building by its address a challenging task. }

An ISBN should be assigned to each title or product, including any backlist or forthcoming titles. Each format or binding must have a separate ISBN (i.e. hardcover, paperbound, VHS video, laserdisc, e-book format, etc). A new ISBN is required for a revised edition. Once assigned, an ISBN can never be reused. An ISBN is printed on the lower portion of the back cover of a book above the bar code and on the copyright page.

^{Almost everything I learned about Word's numbering I learned from the Word newsgroups (especially the Microsoft Word Numbering newsgroup) and from the MS Word MVP FAQ site. The contributions of John McGhie (especially his article about Word's Numbering Explained on the MS Word MVP FAQ site) and Dave Rado are significant. The current page represents a mere summary and application of some of that work. }

__The European system is most widely used. The odd numbers will typically be on the left-hand side as seen from the centre of the town or village, with the lowest numbers at the end of the street closest to the town centre. Intermediate properties usually have a number suffixed A, B, C, etc., much more rarely instead being given a half number, e.g. the old police station at 20 1⁄2 Camberwell Church Street. It is extremely rare for a property (built next to no. 2 after the street had been numbered) to be zero (0) or named Minusone; researchers have found these instances once in Middlesbrough and once in Newbury.[11] In many rural streets, significantly built alongside before 1900, houses remain named (unnumbered).__

# In Australia and New Zealand, the current standard (Australia/New Zealand joint standard AS/NZS 4819:2011 - Rural & Urban Addressing)[6] is directed at local governments that have the primary responsibility for addressing and road naming. The standard calls for lots and buildings on newly created streets to be assigned odd numbers (on the left) and even numbers (on the right) when facing in the direction of increasing numbers (the European system) reflecting already common practice. It first came into force in 2003 under AS/NZS 4819:2003 - Geographic Information – Rural & Urban Addressing.[7] Exceptions are where the road forms part of the boundary between different council areas or cities. For example, Underwood Road in Rochedale South, divided between Logan City and the City of Brisbane.

The two most common errors in handling an ISBN (e.g., typing or writing it) are a single altered digit or the transposition of adjacent digits. It can be proved that all possible valid ISBN-10's have at least two digits different from each other. It can also be proved that there are no pairs of valid ISBN-10's with eight identical digits and two transposed digits. (These are true only because the ISBN is less than 11 digits long, and because 11 is a prime number.) The ISBN check digit method therefore ensures that it will always be possible to detect these two most common types of error, i.e. if either of these types of error has occurred, the result will never be a valid ISBN – the sum of the digits multiplied by their weights will never be a multiple of 11. However, if the error occurs in the publishing house and goes undetected, the book will be issued with an invalid ISBN.[42]

__One of the easiest ways to begin applying numbers is by starting to type a numbered list. Word recognizes that you are creating a list and responds accordingly by converting text that you type into numbered items. The number scheme, delimiter characters that mark the beginning or end of a unit of data and formatting are all based on what you have typed.__

*Where additional buildings are inserted or subdivided, these are often suffixed a, b, c, etc. (in Spain and France, bis, ter, quater). Where buildings are later combined, they may use just one of the original numbers, combine them ("13/15"), or give their address as a range (e.g. "13–17"; not to be construed as including the even numbers 14 and 16). Buildings with multiple entrances may have a single number for the entire building or a separate number for each entrance.*

This check system – similar to the UPC check digit formula – does not catch all errors of adjacent digit transposition. Specifically, if the difference between two adjacent digits is 5, the check digit will not catch their transposition. For instance, the above example allows this situation with the 6 followed by a 1. The correct order contributes 3×6+1×1 = 19 to the sum; while, if the digits are transposed (1 followed by a 6), the contribution of those two digits will be 3×1+1×6 = 9. However, 19 and 9 are congruent modulo 10, and so produce the same, final result: both ISBNs will have a check digit of 7. The ISBN-10 formula uses the prime modulus 11 which avoids this blind spot, but requires more than the digits 0-9 to express the check digit.

^{a concept of quantity that is or can be derived from a single unit, the sum of a collection of units, or zero. Every number occupies a unique position in a sequence, enabling it to be used in counting. It can be assigned to one or more sets that can be arranged in a hierarchical classification: every number is a complex number; a complex number is either an imaginary number or a real number, and the latter can be a rational number or an irrational number; a rational number is either an integer or a fraction, while an irrational number can be a transcendental number or an algebraic numberSee complex number, imaginary number, real number, rational number, irrational number, integer, fraction, transcendental number, algebraic number See also cardinal number, ordinal number }
