At its inception, the acronym LCCN stood for 'Library of Congress Catalog Number'.
Answer: False
The acronym LCCN originally stood for 'Library of Congress Card Number,' reflecting its initial use to identify sets of physical catalog cards.
The Library of Congress originally distributed bibliographic information by selling duplicate sets of physical catalog cards to other libraries.
Answer: True
This practice, known as centralized cataloging, involved the Library of Congress preparing physical cards with bibliographic information and selling duplicate sets to other libraries for their own catalogs.
In the early centralized cataloging system, the LCCN served to identify the specific content of a book rather than the set of bibliographic cards.
Answer: False
The LCCN was assigned to each set of bibliographic cards as a unique serial number, identifying the card set itself, not the content of the book.

An LCCN is fundamentally composed of three parts: a year, a serial number, and a check digit.
Answer: False
In its most basic structure, an LCCN consists of two fundamental parts: a year and a serial number. A check digit was only included as part of an experimental system from 1969-1972.
The year component of an LCCN is always represented by four digits, regardless of the issuance year.
Answer: False
The year component is represented by two digits for numbers issued between 1898 and 2000, and by four digits for those issued from 2001 onwards.
LCCNs from 1898, 1899, and 1900 are differentiated by a unique prefix digit.
Answer: False
These ambiguous years are distinguished from each other by the specific size or length of their associated serial number, not by a prefix.
LCCNs that begin with the digit '7' indicate an experimental system from 1969-1972 that included a check digit.
Answer: True
LCCNs commencing with the digit '7' were part of an experimental system between 1969 and 1972 that incorporated a check digit to detect data entry errors.
The serial number portion of an LCCN is typically six digits long, maintained by leading zeros.
Answer: True
The standard format for the serial number is six digits, with leading zeros used as placeholders to maintain this length.
Older LCCNs always have six digits in their serial number, as leading zeros were always a standard practice.
Answer: False
The practice of padding the serial number with leading zeros to achieve a six-digit length is a more recent addition to the format, so older LCCNs may appear with fewer digits.
The hyphen between the year and serial number in an LCCN is a mandatory formatting element.
Answer: False
The hyphen frequently seen separating the year and serial number is an optional element and not required for the number to be valid.
The Library of Congress currently advises publishers to include a hyphen when presenting LCCNs for clarity.
Answer: False
More recently, the Library of Congress has instructed publishers not to include a hyphen when presenting LCCNs.
The serial number within an LCCN is a unique sequential identifier assigned to each cataloged record within a specific year.
Answer: True
The serial number works in conjunction with the year component to create a distinct control number, serving as a unique sequential identifier for each record cataloged within that year.
A check digit is a random number appended to an LCCN to increase its uniqueness.
Answer: False
A check digit is not random; it is a single digit calculated from the other digits in a number and is used for error detection, not to increase uniqueness.
How is the year component of an LCCN formatted for numbers issued from 2001 onwards?
Answer: Four digits
For LCCNs issued from the year 2001 onwards, the year component is represented by four digits.
How are LCCNs from the ambiguous years of 1898, 1899, and 1900 differentiated from each other?
Answer: By the specific size or length of their associated serial number.
Due to the two-digit year format, these years were ambiguous. They are distinguished from one another by the length of their serial number.
What unique characteristic applies to LCCNs that commence with the digit '7'?
Answer: They were part of an experimental system (1969-1972) that included a check digit.
LCCNs beginning with '7' were part of an experimental system implemented between 1969 and 1972 that included a check digit for error detection.
What is the standard length for the serial number portion of an LCCN?
Answer: Six digits
The serial number portion of an LCCN is typically six digits long, maintained by the inclusion of leading zeros.
Why might older LCCNs sometimes appear with fewer than six digits in their serial number?
Answer: The practice of padding with leading zeros is a more recent addition to the format.
The convention of padding the serial number with leading zeros to achieve a full six-digit length is a more recent practice, so older LCCNs may not adhere to it.
What is the Library of Congress's current recommendation to publishers regarding the use of hyphens in LCCNs?
Answer: Do not include a hyphen when presenting LCCNs.
Although the hyphen is an optional element, the Library of Congress has more recently issued instructions to publishers advising them not to include it.
What is the primary role of the 'serial number' within the structure of an LCCN?
Answer: To serve as a unique sequential identifier assigned to each cataloged record within a given year.
The serial number works with the year component to create a distinct control number, serving as a unique sequential identifier for each record cataloged in that year.

For LCCNs issued between 1898 and 2000, how was the year component formatted?
Answer: Two digits
For LCCNs issued in this period, the year component was represented by two digits, which led to some ambiguity for the years 1898, 1899, and 1900.
What is the main function of a 'check digit' in the context of LCCNs that begin with '7'?
Answer: To detect errors in data entry.
A check digit is a form of redundancy check used to detect errors in data entry. It was part of an experimental system for LCCNs beginning with '7' from 1969-1972.
The practice of padding the serial number portion of an LCCN with leading zeros to achieve six digits is considered what?
Answer: A recent addition to the LCCN format.
