書評

Image
書評 簡言之,即是介紹書籍內容,並評論其得失之謂。根據美國《蘭登字典》解釋:「 書評是對於新出版的書加以批判(Critical description)和評價(evaluation),而發表在報紙或雜誌者。」 而王梅玲則認為書評「係指由評論家或新聞工作者對於新出版圖書給予介紹與評論而在報紙或期刊出版的文章」。 當然,隨著網路科技及出版業的發達與進步,書評的載體已有了變化,形式也越來越多元,並不侷限於有形的產物。 目录 1 類型 2 功能 3 形式 4 參見 5 參考資源 類型 根據洪肇隆在《選書指南》中指出,書評依其寫作方式及所述重點之不同,大略可分為下列六型: 介紹型書評:著力於介紹一書之內容,往往將各章節依次作一說明,而批評較少,嚴格來說宜稱為書介。 論述型書評:將全書內容融會貫通,了然於心之後,將作者想法全盤托出,並加以評論其得失,乃最常見之書評。 摘要型書評:此為將具代表性的內容片段,摘要敘述,並加以評論。因其引原文多,故比較客觀。 源考型書評:多半是專家就專書所作之評論,其學術性大於介紹性,因此寫作者須具備相當學術基礎,此類是最不容易寫的書評。 比較型書評:將同類性質之二本或多本書加以互相比較,以其中一本為主,由與他書之比較中,見出該書之價值優劣。 感想型書評:即常見之讀後感,往往動人以情,常能引發讀者興趣,欲一睹原作,故可讀性極高。 功能 徐召勛認為書評最主要有四大功能: 提高圖書品質 促進學術發展與文藝創作 擴大發行量 指導讀者閱讀 Walford則引用Lester S. King的說法認為,書評主要的功能在於描述與評價:書評向讀者提供書籍內容大致走向,並指出其中優劣所在。 形式 參見 影評 閱讀報告 參考資源 洪肇隆(民70)。選書指南:書評。書府,3,71-74。 徐召勛編(民83)。書評學概論。武昌:武漢大學,1-5。 规范控制 LCCN: sh99001470 NDL: 00572074   這是與 圖書館學 相關的小作品。你可以通过 編輯或修訂 擴充其內容。 This page is only for reference, If you ...

Ironworks

For other uses, see Ironworks (disambiguation). The Iron Rolling Mill ( Eisenwalzwerk ), 1870s, by Adolph Menzel. Casting at an iron foundry: From Fra Burmeister og Wain's Iron Foundry , 1885 by Peder Severin Krøyer An ironworks or iron works is a building or site where iron is smelted and where heavy iron and steel products are made. The term is both singular and plural, i.e. the singular of ironworks is ironworks . Ironworks succeed bloomeries when blast furnaces replaced former methods. An integrated ironworks in the 19th century usually included one or more blast furnaces and a number of puddling furnaces or a foundry with or without other kinds of ironworks. After the invention of the Bessemer process, converters became widespread, and the appellation steelworks replaced ironworks. The processes carried at ironworks are usually described as ferrous metallurgy, but the term siderurgy is also occasionally used. This is derived from the Greek words sideros...

副刊

Image
副刊 ( 英语: Supplement ),廣義來說泛指報紙中所有非新聞性的內容,很多時候是報紙刊登文藝性的版面,但現在也有很多報紙的副刊包括消費及休閒資訊。 副刊可能每天都出版,或是每逢周末假日刊出。副刊的版面大小可能與大報相同,但也有可能與小型報相類似。 歷史 光緒十二年(1886年)起,《字林滬報》總主筆蔡爾康為了應付與《申報》長期以來的競爭劣勢,開始編纂副刊《玉琯鐫新》,這時的副刊只是一些古老詩詞,光緒十三年(1887年),又新增《花團錦簇樓詩稿》一頁。光緒十四年五月(1888年6月)又加刊《詞林畫報》。 光緒二十三年(1897年11月24日),《字林滬報》出版附張《消閑報》,由高太痴主筆,是中國最早的文藝性副刊。此舉大開中國報業的副刊之門,但名稱不盡相同,副刊在早期又稱“文苑”、“餘审”、“丛载”、“餘录”、“谐部”、“说部”、“附张”、“附章”、“附页”、“文艺栏”、“文艺版”、“报尾巴”、“报屁股”、“副张”、“副镌”等。报屁股是對當時副刊的一種衊稱,表示當時副刊實無太多內容。「五四運動」後,新文藝開始吹起反攻號角,著名的副刊有孫伏園《晨報副刊》,宗白華主筆的《時事新報》副刊《學燈》,《民國日報》副刊《覺悟》,黎烈文《申報》的《自由談》和《大公報》的《文藝》,端木蕻良、郁風、吳祖光、夏衍都曾從事過副刊編輯工作。 这是一篇與報紙、印刷業或出版業相關的小作品。你可以通过编辑或修订扩充其内容。 查 论 编 This page is only for reference, If you need detailed information, please check here
