Periodical in the context of "List of the oldest newspapers"

A letter to the editor (LTE) is a letter sent to a publication about an issue of concern to the reader. Usually, such letters are intended for publication. In many publications, letters to the editor may be sent either through conventional mail or electronic mail.

Letters to the editor are most frequently associated with newspapers and news magazines; however, they are sometimes published in other periodicals such as entertainment and technical magazines and academic journals. Radio and television stations may also receive such letters, which are sometimes read on the air, particularly on news commentary broadcasts or on talk radio. In this presentation form the letter to the editor can also be described as viewer mail or listener mail, depending on the medium.

The nameplate (American English) or masthead (British English) of a newspaper or periodical is its designed title as it appears on the front page or cover. Another very common term for it in the newspaper industry is "the flag". It is part of the publication's branding, with a specific font and, usually, color. It may include other details besides the name, such as ornamentation, a subtitle, or motto. For example, the masthead of The Times of London includes the British Royal Arms between the words "The" and "Times". Another example is the masthead of Daily Record of Scotland, which includes an ornamental lion in the "rampant" attitude to the right of the word "Daily".

A government gazette (also known as an official gazette, official journal, official newspaper, official monitor or official bulletin) is a periodical publication that has been authorised to publish public or legal notices. It is usually established by statute or official action, and publication of notices within it, whether by the government or a private party, is usually considered sufficient to comply with legal requirements for public notice.

Gazettes are published either in print, electronically or both.

A journal, from the Old French journal (meaning "daily"), may refer to:

• Bullet journal, a method of personal organization
• Diary, a record of personal secretive thoughts and as open book to personal therapy or used to feel connected to oneself. A record of what happened over the course of a day or other period
• Daybook, also known as a general journal, a daily record of financial transactions
• Logbook, a record of events important to the operation of a vehicle, facility, or otherwise
• Transaction log, a chronological record of data processing
• Travel journal, a record of the traveller's experience during the course of their journey

In publishing, journal can refer to various periodicals or serials:

A pamphlet is an unbound book (that is, without a hard cover or binding). Pamphlets may consist of a single sheet of paper that is printed on both sides and folded in half, in thirds, or in fourths, called a leaflet or it may consist of a few pages that are folded in half and saddle stapled at the crease to make a simple book.

In the "International Standardization of Statistics Relating to Book Production and Periodicals", UNESCO defines a pamphlet as "a non-periodical printed publication of 5 to 48 pages, excluding covers, published in a specific country and available to the public," while a book is "a non-periodical printed publication of at least 49 pages, excluding covers." These definitions are intended solely for UNESCO's book production statistics.

The Gentleman's Magazine was a monthly magazine founded in London, England, by Edward Cave in January 1731. It ran uninterrupted for almost 200 years, until 1907, ceasing publication altogether in 1922. It was the first to use the term magazine (from the French magazine, meaning "storehouse") for a periodical. Samuel Johnson's first regular employment as a writer was with The Gentleman's Magazine.

A professional magazine or professional journal is a periodical published by the governing body of a profession. The standard of quality of such a periodical may be similar to that of a scholarly publication.

A professional journal is said to be one which is "published by the profession and for the profession", which cannot be charged with being dominated by trade, and which "serves a higher and therefore a better use" than a so-called trade journal "by printing in an unbiased way the subject matter".
