diary

we may write or note the important things in diary in day to day basis.
A diary is a record (originally in handwritten format) with discrete entries arranged by date reporting on what has happened over the course of a day or other period. A personal diary may include a person's experiences, and/or thoughts or feelings, including comment on current events outside the writer's direct experience. Someone who keeps a diary is known as a diarist. Diaries undertaken for institutional purposes play a role in many aspects of human civilization, including government records (e.g., Hansard), business ledgers and military records.
Generally the term is today employed for personal diaries, normally intended to remain private or to have a limited circulation amongst friends or relatives. The word "journal" may be sometimes used for "diary," but generally a diary has (or intends to have) daily entries, whereas journal-writing can be less frequent.
Whilst a diary may provide information for a memoir, autobiography or biography, it is generally written not with the intention of being published as it stands, but for the author's own use. In recent years, however, there is internal evidence in some diaries (e.g., those of Ned Rorem, Alan Clark, Tony Benn or Simon Gray) that they are written with eventual publication in mind, with the intention of self-vindication (pre- or posthumous) or simply for profit.
By extension the term diary is also used to mean a printed publication of a written diary; and may also refer to other terms of journal including electronic formats (e.g., blogs).
As internet access became commonly available, many people adopted it as another medium in which to chronicle their lives with the added dimension of an audience. The first online diary is thought to be Claudio Pinhanez's "Open Diary," published at the MIT Media Lab website from 14 November 1994 until 1996.^[1] Other early online diarists include Justin Hall, who began eleven years of personal online diary-writing in 1994,^[2] Carolyn Burke, who started publishing "Carolyn's Diary" on 3 January 1995,^[3] and Bryon Sutherland, who announced his diary The Semi-Existence of Bryon in a USENET newsgroup on 19 April 1995.^[4]
Web-based services such as Open Diary (started in October, 1998) and LiveJournal (January, 1999) soon appeared to streamline and automate online publishing, but growth in personal storytelling came with the emergence of blogs. While the format first focused on external links and topical commentary, widespread blogging tools were quickly used to create web journals. Recent advances have also been made to enable the privacy of internet diary entries. For example, some diary software now stores entries in encrypted format, such 256-bit AES (Advanced Encryption Standard) encryption, and others only permit access to the diary after correct PIN entry on a secure USB device.

maps

To know the location of any places, we use the maps.
A map is a visual representation of an area—a symbolic depiction highlighting relationships between elements of that space such as objects, regions, and themes.
Many maps are static two-dimensional, geometrically accurate (or approximately accurate) representations of three-dimensional space, while others are dynamic or interactive, even three-dimensional. Although most commonly used to depict geography, maps may represent any space, real or imagined, without regard to context or scale; e.g. brain mapping, DNA mapping, and extraterrestrial mapping.
Cartography or map-making is the study and practice of crafting representations of the Earth upon a flat surface (see History of cartography), and one who makes maps is called a cartographer.
Road maps are perhaps the most widely used maps today, and form a subset of navigational maps, which also include aeronautical and nautical charts, railroad network maps, and hiking and bicycling maps. In terms of quantity, the largest number of drawn map sheets is probably made up by local surveys, carried out by municipalities, utilities, tax assessors, emergency services providers, and other local agencies. Many national surveying projects have been carried out by the military, such as the British Ordnance Survey (now a civilian government agency internationally renowned for its comprehensively detailed work).
In addition to location information maps may also be used to portray contour lines (isolines) indicating constant values of elevation, temperature, rainfall, etc.
The orientation of a map is the relationship between the directions on the map and the corresponding compass directions in reality. The word "orient" is derived from Latin oriens, meaning East. In the Middle Ages many maps, including the T and O maps, were drawn with East at the top (meaning that the direction "up" on the map corresponds to East on the compass). Today, the most common – but far from universal – cartographic convention is that North is at the top of a map.

notebooks

Notebooks are the things, which are used for noting the important things.
Artists often use large notebooks which include wide spaces of blank paper appropriate for drawing. Lawyers use rather large notebooks known as legal pads that contain lined paper (often yellow) and are appropriate for use on tables and desks. These horizontal lines or "rules" are sometimes classified according to their space apart with "wide rule" the farthest, "college rule" closer, "legal rule" slightly closer and "narrow rule" closest, allowing more lines of text per page. When sewn into a pasteboard backing, these may be called composition books, or in smaller signatures may be called "blue books" or exam books and used for essay exams. In contrast, journalists prefer small, hand-held notebooks for portability (reporters' notebooks), and sometimes use shorthand when taking notes. Scientists and other researchers use lab notebooks to document their experiments. The pages in lab notebooks are sometimes graph paper to plot data. Police officers are required to write notes on what they observe, using a police notebook. Land surveyors commonly record field notes in durable, hard-bound notebooks called "field books."
Notebook pages can be recycled via standard paper recycling. Recycled notebooks are available, differing in recycled percentage and paper quality.

books

A book is a set of written, printed, illustrated, or blank sheets, made of ink, paper, parchment, or other materials, usually fastened together to hinge at one side. A single sheet within a book is called a leaf, and each side of a leaf is called a page. A book produced in electronic format is known as an electronic book (e-book).
Books may also refer to works of literature, or a main division of such a work. In library and information science, a book is called a monograph, to distinguish it from serial periodicals such as magazines, journals or newspapers. The body of all written works including books is literature. In novels and sometimes other types of books (for example, biographies), a book may be divided into several large sections, also called books (Book 1, Book 2, Book 3, and so on). A lover of books is usually referred to as a bibliophile or, more informally, a bookworm.
A store where books are bought and sold is a bookstore or bookshop. Books can also be borrowed from libraries. In 2010, Google estimated that since the invention of printing, approximately 130,000,000 unique titles had been published.^[2]
The methods used for the printing and binding of books continued fundamentally unchanged from the 15th century into the early years of the 20th century. While there was of course more mechanization, Gutenberg would have had no difficulty in understanding what was going on if he had visited a book printer in 1900.
Gutenberg's invention was the use of movable metal types, assembled into words, lines, and pages and then printed by letterpress. In letterpress printing ink is spread onto the tops of raised metal type, and is transferred onto a sheet of paper which is pressed against the type. Sheet-fed letterpress printing is still available but tends to be used for collector's books and is now more of an art form than a commercial technique (see Letterpress).
Modern paper books are printed on papers which are designed specifically for the publication of printed books. Traditionally, book papers are off white or low white papers (easier to read), are opaque to minimise the show through of text from one side of the page to the other and are (usually) made to tighter caliper or thickness specifications, particularly for case bound books. Typically, books papers are light weight papers 60 to 90 g/m² and often specified by their caliper/substance ratios (volume basis). For example, a bulky 80 g/m² paper may have a caliper of 120 micrometres (0.12 mm) which would be Volume 15 (120×10/80) whereas a low bulk 80 g/m² may have a caliper of 88 micrometres, giving a volume 11. This volume basis then allows the calculation of a books PPI (printed pages per inch) which is an important factor for the design of book jackets and the binding of the finished book. Different paper qualities are used as book paper depending on type of book
Books are the things, which are needed to increase the knowledge of the individual or of any.
