Cassette tape in the context of "Library"

An audiobook (or a talking book) is a recording of a book or other work being read out loud. A reading of the complete text is described as "unabridged", while readings of shorter versions are abridgements.

Spoken audio has been available in schools and public libraries and to a lesser extent in music shops since the 1930s. Many spoken word albums were made prior to the age of cassettes, compact discs, and downloadable audio, often of poetry and plays rather than books. It was not until the 1980s that the medium began to attract book retailers, and then book retailers started displaying audiobooks on bookshelves rather than in separate displays.

A slipcase is a five-sided box, usually made of high-quality cardboard, into which binders, books or book sets are slipped for protection, leaving the spine exposed. Special editions of books are often slipcased for a stylish appearance when placed on a bookshelf. A few publishers, such as the Folio Society, publish nearly all their books in slipcases.

Protective slipcases have been issued for records, cassettes, 8-track tapes, film, video cassettes, compact discs, DVDs and even toys instead of or in addition to the more common jewel cases or keep case, and may be chosen for aesthetic or economic reasons. Larger slipcases that are designed to house one or more items are often used in packaging for special edition releases or box sets.

An album is a collection of audio recordings (e.g., music) issued on a medium such as compact disc (CD), vinyl (record), audio tape (like 8-track or cassette), or digital. Albums of recorded sound were developed in the early 20th century as individual 78 rpm records (78s) collected in a bound book resembling a photo album; this format evolved after 1948 into single vinyl long-playing (LP) records played at 33+1⁄3 rpm.

The album was the dominant form of recorded music expression and consumption from the mid-1960s to the early 21st century, a period known as the album era. Vinyl LPs are still issued, though album sales in the 21st-century have mostly focused on CD and MP3 formats. The 8-track tape was the first tape format widely used alongside vinyl from 1965 until being phased out by 1983, being gradually supplanted by the cassette tape throughout the 1970s and early 1980s; the popularity of the cassette reached its peak during the late 1980s before sharply declining during the 1990s. The cassette had largely disappeared by the first decade of the 2000s.

The album era (sometimes, album-rock era) was a period in popular music, usually defined as the mid-1960s through the middle of the 2000s decade, in which the album—a collection of songs issued on physical media—was the dominant form of recorded music expression and consumption. It was driven primarily by three storage formats: the 33⅓ rpm long-playing record (LP), the cassette tape, and the compact disc (CD). Rock musicians from the United States and the United Kingdom were often at the forefront of the era. The term "album era" is also used to refer to the marketing and aesthetic period surrounding a recording artist's release of an album.

Long-playing record albums, first released in 1948, offered the ability to sell larger amounts of music than singles. The album era arrived in earnest in the mid-1960s, when the Beatles began to release artistically ambitious and top-selling LPs. The industry embraced albums to immense success, and burgeoning rock criticism validated their cultural value. By the 1970s, the LP had emerged as a fundamental artistic unit and a widely popular item with young people. Some were concept albums, especially by progressive musicians in rock and soul.

A portable media player (PMP) or digital audio player (DAP) is a portable consumer electronics device capable of storing and playing digital media such as audio, images, and video files. Normally, they refer to small, battery-powered devices utilising flash memory or a hard disk for storing various media files. MP3 players has been a popular alternative name used for such devices, even if they also support other file formats and media types other than MP3 (for example AAC, FLAC, WMA).

Generally speaking, PMPs are equipped with a 3.5 mm headphone jack which can be used for headphones or to connect to a boombox, home audio system, or connect to car audio and home stereos wired or via a wireless connection such as Bluetooth, and some may include radio tuners, voice recording and other features. In contrast, analogue portable audio players play music from non-digital media that use analogue media, such as cassette tapes or vinyl records. As devices became more advanced, the PMP term was later introduced to describe players with additional capabilities such as video playback (they used to also be called "MP4 players"). The PMP term has also been used as an umbrella name to describe any portable device for multimedia, including physical formats (such as portable CD players) or handheld game consoles with such capabilities.

A bobbin or spool is a spindle or cylinder, with or without flanges, on which yarn, thread, wire, tape or film is wound. Bobbins are typically found in industrial textile machinery, as well as in sewing machines, fishing reels, tape measures, film rolls, cassette tapes, within electronic and electrical equipment, and for various other applications.
