1. A quotation is the repetition of one expression as part of another one, particularly when the quoted expression is well-known or explicitly attributed by citation to its original source, and it is indicated by (punctuated) with quotation marks.
2. A quotation can also refer to the repeated use of units of any other form of expression, especially parts of artistic works: elements of a painting, scenes from a movie or sections from a musical composition.
3. Quotations are used for a variety of reasons: to illuminate the meaning or to support the arguments of the work in which it is being quoted, to provide direct information about the work being quoted (whether in order to discuss it, positively or negatively), to pay homage to the original work or author, to make the user of the quotation seem well-read, and/or to comply with copyright law.
4. Quotations are also commonly printed as a means of inspiration and to invoke philosophical thoughts from the reader. Diaries and calendars often include quotations for entertainment or inspirational purposes, and small, dedicated sections in newspapers and weekly magazines—with recent quotations by leading personalities on current topics—have also become commonplace.
5. The internet has given rise to any number of personal quotation collections that continue to flourish, though sometimes, few of them does not seem to facilitate accurate information or correct citation. Quotations are now popular in social networking messaging. In all these cases, quotations are usually included to give a glimpse of the user’s personality, to make a statement of their beliefs, or to spread views and ideas.
6. The sheer bulk of online quotations, combined with more efficient search engines, has effectively made the Internet the world’s quotation storehouse, encompassing an unprecedented number of easily obtainable quotations.
