A literary magazine is a periodical devoted to literature in a broad sense.
 Literary magazines usually publish short stories, poetry, and essays, along with literary criticism, book reviews, biographical profiles of authors, interviews and letters.
 Literary magazines are often called literary journals, or little magazines, terms intended to contrast them with larger, commercial magazines.
In Denmark there are various magazines with different frequency types, including weekly magazines, monthly magazines and quarterly magazines.
 As in other Nordic countries, the national consumer organizations publish their magazines in Denmark.
 In 2007, there were nearly 68 consumer magazines in the country which were mostly owned by Danish media groups.
 Of them 52 were monthly/quarterly whereas 16 were weekly.
 These magazines were grouped into four main categories: general-interest magazines, opinion magazines, TV and radio guides, and professional and scientific magazines.
Consideration is the central concept in the common law of contracts and is required, in most cases, for a contract to be enforceable.
 Consideration is the price one pays for another's promise.
 It can take a number of forms: money, property, a promise, the doing of an act, or even refraining from doing an act.
 In broad terms, if one agrees to do something he was not otherwise legally obligated to do, it may be said that he has given consideration.
 For example, Jack agrees to sell his car to Jill for $100.
 Jill's payment of $100 (or her promise to do so) is the consideration for Jack's promise to give Jill the car, and Jack's promise to give Jill the car is consideration for Jill's payment of $100.

A door knocker is an item of door furniture that allows people outside a house to alert those inside to their presence.
 A door knocker has a part fixed to the door, and a part (usually metal) which is attached to the door by a hinge, and may be lifted and used to strike a plate fitted to the door, or the door itself, making a noise.
 The struck plate, if present, would be supplied and fitted with the knocker.
 Door knockers are often ornate, but may be no more than a simple fitting with a metal bob, or ring.
