　　Reed Elsevier
　　Reed Elsevier has a proud heritage stretching back to the late 19th century and to the pioneering work of two industrialists, one English, one Dutch.
　　Albert E Reed laid part of the foundations of what is today Reed Elsevier when he set up a newsprint manufacturing plant in England in 1894. His business became a public company under his own name in 1903
　　It was not until 1970 that the company was renamed Reed International Limited. It expanded through merger and acquisitions and by producing industrial magazines through its subsidiary IPC Business Press Ltd and consumer magazines through IPC Magazines Ltd. In 1982 the name changed again to Reed International PLC and, in 2002, to Reed Elsevier PLC.
　　Other foundations for the group were laid in 1880, when Jacobus George Robbers set up a publishing company in Rotterdam. He called it Elsevier after a 16th Century family of booksellers and printers who had, among other things, published the works of the Dutch philosopher, Erasmus.
　　In 1951, Elsevier Press Inc was set up in the US. Some ten years later offices had been opened in New York and London. The rapid growth continued in the 1970s and by the end of that decade the company had been renamed Elsevier Scientific Publishers. Other acquisitions and mergers continued this growth, including the purchase of the UK’s Pergamon Press in 1991, two years before the merger that created Reed Elsevier.
　　It has three target markets – Science and Medical(20.59 and 21.45 billion$, ), Legal and Risk Management(15.79 billion$, ), and Business publishing( 21.99billion$, ).

    兼并是它实现多种经营的基本手段。除了多元化的经营理念、以人为本（human-oriented ）的服务理念外，为了适应时代的进步和要求，积极应用信息技术、提供各类电子解决方案，积极拓展国际市场也成为汤姆森集团重要的发展理念。
　　汤姆森是全球主要的金融信息提供商之一。目前在全球雇员人数约为3.2万，去年销售收入66亿美元。该集团创办者罗伊•汤姆森上世纪30年代着手建造他的传媒王国。目前，以戴维•汤姆森为首的汤姆森家族拥有220亿美元资产，是世界第10大富豪。
　　路透其历史可追溯到1849年，当时，德裔移民保罗•路透通过他的45只信鸽，在德国亚琛与比利时的布鲁塞尔之间传递股市行情。经过一个半世纪的发展，路透集团已发展为一个集新闻信息、财经服务、投资管理于一身的大型跨国公司。
　　2008年，汤姆森成功并购路透，合并后的新公司年收入达到约60亿英镑，从而取代美国彭博新闻社，成为全球最大金融信息服务提供商。两家公司合并后，路透现任首席执行官汤姆•格洛瑟将成为新公司首席执行官。新公司将拥有4．9万名员工，年收入约为120亿美元，在全球金融信息市场占据约34%的份额。

大学出版
　　英国的大学出版是伴随着学术出版而发展起来的，二次世界大战以后，随着英国国内高等教育的发展，学术出版业也获得了发展的机会。到20世纪60年代，英国形成了一个较为完善的学术出版业。
　　除了一牛津大学出版社（Oxford University Press, OUP）和剑桥大学出版社(Cambridge University Press, CUP)为首的主力军外，市场上还活跃着众多商业出版社如麦克米伦出版公司( Macmillian )、路特里奇与克干×保罗出版社( Routledge & Kegan Paul )、布莱克维尔出版社(Black-well)、米苏恩出版社(Methuen)、爱德华×阿诺出版社(Edward Arnold)以及艾伦×昂文出版社(Allen & Unwin)等。
　　从20世纪70年代开始，因果的学术出版逐渐发生变化，在70年代初，英国出现了几家新的出版公司，如哈维斯特出版社（Harvester）,这些出版社主要致力于开拓学术书籍的出口市场，尤其是北美图书馆市场。80年代初期，由于英国国内图书馆消减学术专著的购买量，这一市场开始萎缩。英国中小学术出版社库存猛增，加之1979年的经济危机导致学术出版社之间的购并。到了20世纪90年代，英国学术出版业经过重组、形成了6家出版巨头。他们分别是OUP, CUP, Macmillian, Routledge & Kegan Paul (Tomson) ,Black-well and Longman(Pearson).这6巨头左右了英国4亿英镑的学术出版市场。
　　牛津和剑桥出版社免于被收购主要归功于政府政策倾斜，当然离不开出版社自身的开拓，他们对英国的学术出版和世界学术出版的双子星座，他们的历史和现状从某种意义上来说代表了英国乃至世界学术出版的历史和现状。
　　牛津大学创办于1478年，已有500多年的历史，年营业额达到5000多万英镑，从业人员2000有人，出版社分为4个部门，即专业书部、一般书部、教育部和国际部。其中专业书部的规模最大。
