Whitaker's is a reference book, published annually in the United Kingdom. The book was originally published by J Whitaker & Sons from 1868 to 1997, then by The Stationery Office until 2003, and then by A & C Black which became a wholly owned subsidiary of Bloomsbury Publishing in 2011. The 149th edition of Whitaker's was published on 17 November 2016.
Joseph Whitaker began preparing his Almanack in the autumn of 1868. He postponed publication of the first edition on learning of the resignation of Benjamin Disraeli on 1 December 1868, so that he could include details of the new Gladstone administration. At the same time, Whitaker continued to expand the information so that the initially planned 329 pages grew to 370. The first edition of the Almanack appeared on 23 December 1868, priced at 1 shilling, introduced by a short editorial piece written by Joseph Whitaker. It began "The Editor does not put forward this Almanack as perfect: yet he ventures to think that he has succeeded in preparing a work which will commend itself to those who desire to see improvement in this direction." It concluded by inviting critics to suggest ways in which improvements could be made. The Manchester Guardian, reviewing the first edition, described it as "the largest of the cheap almanacks" to appear, and noted it contained a great deal more valuable information than other such works. In 2013, the 2014 edition became the first to be published under the new simpler branding of "Whitaker's".
Whitaker's Almanack consists of articles, lists and tables on a wide range of subjects including education, the peerage, government departments, health and social issues, and the environment.
The largest section is the countries directory, which includes recent history, politics, economic information and culture overviews. Each edition also features a selection of critical essays focusing on events of the previous year. Extensive astronomical data covering the forthcoming year is published at the rear of the book.
