A ledger is a book or collection of accounts in which accounting transactions are recorded. Each account has:
Bookbinding is the process of building a book, usually in codex format, from an ordered stack of paper sheets with one's hands and tools, or in modern publishing, by a series of automated processes. To bind a book, groups of pages are joined together, often by thread or adhesive but other options exist such as loose-leaf rings, binding posts, twin-loop spine coils, plastic spiral coils, and plastic spine combs. A cover to protect the contents, usually bearing publication information such as title and author, is generally attached; this can be as simple as a single sheet of paper or an elaborate construction of boards covered in cloth, leather, parchment, etc. with many types of decoration. Processes of making books vary significantly by time period and geography/culture. Mechanised bookbinding was introduced in the 19th century with the industrial revolution, alongside machine papermaking, faster methods of leather tanning, and other changes in manufacturing that affected the book.
The trade of bookbinding includes the binding of blank books and printed books. Blank books, or stationery bindings, are books planned to be written in. These include accounting ledgers, guestbooks, logbooks, notebooks, manifold books, day books, diaries, and sketchbooks. Printed books are produced through letterpress printing, offset lithography, or other printing techniques and their binding practices include fine binding, edition binding, publisher's bindings, and library binding.
A diary is a written or audiovisual memorable record, with discrete entries arranged by date reporting on what has happened over the course of a day or other period. Diaries have traditionally been handwritten but are now also often digital. A personal diary may include a person's experiences, thoughts, and/or feelings, excluding comments 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. In British English, the word may also denote a preprinted journal format.
Today the term is generally 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 (from the Latin word for 'day'), whereas journal-writing can be less frequent.
A library catalog (or library catalogue in British English) is a register of all bibliographic items found in a library or group of libraries, such as a network of libraries at several locations. A catalog for a group of libraries is also called a union catalog. A bibliographic item can be any information entity (e.g., books, computer files, graphics, realia, cartographic materials, etc.) that is considered library material (e.g., a single novel in an anthology), or a group of library materials (e.g., a trilogy), or linked from the catalog (e.g., a webpage) as far as it is relevant to the catalog and to the users (patrons) of the library.
The earliest library catalogs were lists, handwritten or enscribed on clay tablets and later scrolls of parchment or paper. As codices (books with pages) replaced scrolls, so too did library catalogs become like handwritten ledgers and, in some cases, printed books. During the late 18th century through mid-19th century, cataloguing on paper slips or cards gradually replaced ledgers and books as the main medium for library catalogs, and in the 20th it was long ubiquitous. The card catalog was a familiar sight to library users for generations. Computerized cataloguing developed gradually from the mid-20th, and by the late 20th and early 21st, it had mostly replaced card catalogs. The advent of the web brought about ubiquitous use of online public access catalogs (OPACs). Some people still informally refer to the online catalog as a "card catalog".
A bank of issue, also referred to as a note-issuing bank or issuing authority, is a financial institution that issues banknotes.
The short-lived Stockholms Banco (1657–1667) printed notes from 1661 onwards and is generally viewed as the first-ever bank of issue. Banks of issue are thus a more recent creation than transfer or giro banks, which create money in accounts on a ledger, the oldest recorded being the Taula de canvi de Barcelona established in 1401.
A cryptocurrency (colloquially crypto) is a digital currency designed to work through a computer network that is not reliant on any central authority, such as a government or bank, to uphold or maintain it. However, a type of cryptocurrency called a stablecoin may rely upon government action or legislation to require that a stable value be upheld and maintained.
Individual coin ownership records are stored in a digital ledger or blockchain, which is a computerized database that uses a consensus mechanism to secure transaction records, control the creation of additional coins, and verify the transfer of coin ownership. The two most common consensus mechanisms are proof of work and proof of stake. Despite the name, which has come to describe many of the fungible blockchain tokens that have been created, cryptocurrencies are not considered to be currencies in the traditional sense, and varying legal treatments have been applied to them in various jurisdictions, including classification as commodities, securities, and currencies. Cryptocurrencies are generally viewed as a distinct asset class in practice.
Debits and credits in double-entry bookkeeping are entries made in account ledgers to record changes in value resulting from business transactions. A debit entry in an account represents a transfer of value to that account, and a credit entry represents a transfer from the account. Each transaction transfers value from credited accounts to debited accounts. For example, a tenant who writes a rent cheque to a landlord would enter a credit for the bank account on which the cheque is drawn, and a debit in a rent expense account. Similarly, the landlord would enter a credit in the rent income account associated with the tenant and a debit for the bank account where the cheque is deposited.
Debits typically increase the value of assets and expense accounts and reduce the value of liabilities, equity, and revenue accounts. Conversely, credits typically increase the value of liability, equity, and revenue accounts and reduce the value of asset and expense accounts.
The Medici Bank (Italian: Banco dei Medici [ˈbaŋko dei ˈmɛːditʃi]) was a financial institution created by the Medici family in Italy during the 15th century (1397–1494). It was the largest and most respected bank in Europe during its prime. There are some estimates that the Medici family was, for a period of time, the wealthiest family in Europe. Estimating their wealth in today's money is difficult and imprecise, considering that they owned art, land, and gold. With this monetary wealth, the family acquired political power initially in Florence, and later in the wider spheres of Italy and Europe.
A notable contribution to the professions of banking and accounting pioneered by the Medici Bank was the improvement of the general ledger system through the development of the double entry system of tracking debits and credits or deposits and withdrawals.
