The Bank for International Settlements (BIS) is an international financial institution owned by central banks which "fosters international monetary and financial cooperation and serves as a bank for central banks".
The International Journal of Central Banking (IJCB) is an economic research journal which began in the 2004 decision of several Central Banks to create a professional journal for policymakers and researchers in the field of monetary policy.
 In July 2004, the Bank for International Settlements (BIS), the European Central Bank, and each of the Group of Ten (G-10) central banks announced their plans to support the development of a new publication focused on central bank theory and practice.
 Other central banks were invited to participate in this joint project, and there are now some 50 sponsoring institutions.
De Nederlandsche Bank (DNB, "The Dutch Bank", sometimes misdescribed as the "Dutch National Bank" to fit the acronym in English) is the central bank of the Netherlands.
 It is part of the European System of Central Banks (ESCB).
 De Nederlandsche Bank (DNB) is a public limited company (Dutch: naamloze vennootschap) whose every day policy is overseen by the Governing Board.
 Being an NV, DNB has a Supervisory Board (Dutch Raad van Commissarissen).
 In addition, there is an advisory body called the Bank Council (Dutch Bankraad).
 As a public entity the DNB has a function as both part of the European System of Central Banks (ESCB) and an independent public body (zelfstandig bestuursorgaan).
A specimen banknote is printed generally in very limited quantities for distribution to central banks to aid in the recognition of banknotes from a country other than their own.
 In some cases, specimen banknotes are printed in less limited quantities distributed to commercial banks, or even to commercial enterprises and the public at large in order to familiarize users about new designs.
 In addition, specimen banknotes are sold in some countries to collectors (often in special commemorative folders or albums).
 They have also been distributed by banknote printers (such as the American Bank Note Company) as examples of their craftsmanship.
 Occasionally, specimen banknotes are distributed as gifts to dignitaries or to employees of central banks, often in special presentation albums.
Bank reserves are a commercial banks' holdings of deposits in accounts with a central bank (for instance the European Central Bank or the applicable branch bank of the Federal Reserve System, in the latter case including federal funds), plus currency that is physically held in the bank's vault ("vault cash").
 Some central banks set minimum reserve requirements, which require banks to hold deposits at the central bank equivalent to at least a specified percentage of their liabilities such as customer deposits.
 Even when there are no reserve requirements, banks often opt to hold some reserves—called desired reserves—against unexpected events such as unusually large net withdrawals by customers or bank runs.
A central bank, reserve bank, or monetary authority is an institution that manages a state's currency, money supply, and interest rates. Central banks also usually oversee the commercial banking system of their respective countries.
 In contrast to a commercial bank, a central bank possesses a monopoly on increasing the monetary base in the state, and usually also prints the national currency, which usually serves as the state's legal tender.
 Central banks also act as a "lender of last resort" to the banking sector during times of financial crisis.
 Most central banks usually also have supervisory and regulatory powers to ensure the solvency of member institutions, prevent bank runs, and prevent reckless or fraudulent behavior by member banks.

 The Reichsbank was a privately owned central bank of Prussia, under close control by the Reich government.
 Its first president was Hermann von Dechend.
 Before unification in 1871, Germany had 31 central banks – the Notenbanken (note banks).
 Each of the independent states issued their own money.
 In 1870, a law was passed that forbade the formation of further central banks.
 In 1874, a draft banking law was introduced in the Reichstag (the German parliament).
 After several changes and compromises, the law was passed in 1875.
 Despite the creation of the Reichsbank, however, four of the "Notenbanken" – Baden, Bavaria, Saxony and Württemberg – continued to exist until 1914.
