In 1808, the library began as a collection of about 100 books by Samuel Morse. He was a portrait artist and had an interest in developing a circulating library. By 1852, the collection, entitled the Citizen's Library, amassed 425 books. The Morse Institute Library was instituted in 1862 by Mary Ann Morse, Samuel Morse's granddaughter.
Project Gutenberg ( PG) is a volunteer effort to digitize and archive cultural works, as well as to "encourage the creation and distribution of eBooks ." [2] It was founded in 1971 by American writer Michael S. Hart and is the oldest digital library. [3] Most of the items in its collection are the full texts of books or individual stories in ...
Morse code. Morse code is a telecommunications method which encodes text characters as standardized sequences of two different signal durations, called dots and dashes, or dits and dahs. [3] [4] Morse code is named after Samuel Morse, one of the early developers of the system adopted for electrical telegraphy .
Add-on 455 kHz homemade BFO board. In a radio receiver, a beat frequency oscillator or BFO is a dedicated oscillator used to create an audio frequency signal from Morse code radiotelegraphy ( CW) transmissions to make them audible. The signal from the BFO is mixed with the received signal to create a heterodyne or beat frequency which is heard ...
Open Library. Open Library is an online project intended to create "one web page for every book ever published". Created by Aaron Swartz, [ 3][ 4] Brewster Kahle, [ 5] Alexis Rossi, [ 6] Anand Chitipothu, [ 6] and Rebecca Malamud, [ 6] Open Library is a project of the Internet Archive, a nonprofit organization.
In computer science and information theory, a Huffman code is a particular type of optimal prefix code that is commonly used for lossless data compression.The process of finding or using such a code is Huffman coding, an algorithm developed by David A. Huffman while he was a Sc.D. student at MIT, and published in the 1952 paper "A Method for the Construction of Minimum-Redundancy Codes".
LibriVox is a group of worldwide volunteers who read and record public domain texts, creating free public domain audiobooks for download from their website and other digital library hosting sites on the internet. It was founded in 2005 by Hugh McGuire to provide "Acoustical liberation of books in the public domain" [ 2] and the LibriVox ...
Morse code mnemonics are systems to represent the sound of Morse characters in a way intended to be easy to remember. Since every one of these mnemonics requires a two-step mental translation between sound and character, none of these systems are useful for using manual Morse at practical speeds. Amateur radio clubs can provide resources to ...
