1 " It had been a slow and painful business, discovering that the theory of love did not match the reality of life. It was like expecting to be able to write a symphony because you had once read a handbook of composition. "
― Julian Barnes , The Noise of Time
2 " Sang Ly, we are literature-our lives, our hopes, our desires, our despairs, our passions, our strengths, our weaknesses. Stories express our longing not only to make a difference today but to see what is possible for tomorrow. Literature has been called a handbook for the art of being human. "
― Camron Wright , The Rent Collector
3 " If you need a handbook for praise and worship, read Psalms. "

4 " Maxwell D. Kalist is a receiving teller at a city bank, Orwell and Finch, where he runs an efficient department of twenty two clerks and twelve junior clerks. He carries a leather-bound vade mecum everywhere with him – a handbook of the most widely contravened banking rules. He works humourlessly (on the surface of it) in a private, perfectly square office on the third floor of a restored grain exchange midway along the Eastern flank of Květniv’s busy, modern central plaza. Behind his oblong slate desk and black leather swivel chair is an intimidating, three-storey wall made almost entirely of bevelled, glare-reducing grey glass in art-deco style; one hundred and thirty six rectangles of gleam stacked together in a dangerously heavy collage. "

5 " Two writings of al-Hassār have survived. The first, entitled Kitāb al-bayān wa t-tadhkār [Book of proof and recall] is a handbook of calculation treating numeration, arithmetical operations on whole numbers and on fractions, extraction of the exact or approximate square root of a whole of fractionary number and summation of progressions of whole numbers (natural, even or odd), and of their squares and cubes. Despite its classical content in relation to the Arab mathematical tradition, this book occupies a certain important place in the history of mathematics in North Africa for three reasons: in the first place, and notwithstanding the development of research, this manual remains the most ancient work of calculation representing simultaneously the tradition of the Maghrib and that of Muslim Spain. In the second place, this book is the first wherein one has found a symbolic writing of fractions, which utilises the horizontal bar and the dust ciphers i.e. the ancestors of the digits that we use today (and which are, for certain among them, almost identical to ours) [Woepcke 1858-59: 264-75; Zoubeidi 1996]. It seems as a matter of fact that the utilisation of the fraction bar was very quickly generalised in the mathematical teaching in the Maghrib, which could explain that Fibonacci (d. after 1240) had used in his Liber Abbaci, without making any particular remark about it [Djebbar 1980 : 97-99; Vogel 1970-80]. Thirdly, this handbook is the only Maghribian work of calculation known to have circulated in the scientific foyers of south Europe, as Moses Ibn Tibbon realised, in 1271, a Hebrew translation.[Mathematics in the Medieval Maghrib: General Survey on Mathematical Activities in North Africa] "
