Record collecting is the hobby of collecting sound recordings, usually of music, but sometimes poetry, reading, historical speeches, and ambient noises. Although the typical focus is on vinyl records, all formats of recorded music can be collected.
The scope of a record collection may include a focus on any of the following categories:
genres (or subgenres)
artists (or producers)
recording labels (or sublabels)
periods (or music scenes)
formats, e.g. 78s, 7"s, LPs, EPs, Mono, Reel-to-reel, Cassettes, 45s, SPs, CDs, etc.
specialisms, e.g. unusual physical specimens (odd shapes, colors, sizes, speeds) regardless of recorded content, records having original "stock" generic sleeves identifying the label, variations in the record's label design as issued by particular companies, or imported copies. Demand is usually highest for the "original" or earliest pressings of records, often identified by variations in the label or cover. Avid collectors develop specialized knowledge about such details.
One collectible record format is known as a test pressing. Five to 10 initial copies are often pressed for the purpose of checking the mix or levels on a record, or to ensure that the die is cutting properly. Though usually meant for the artist, producer, pressing plant, or record label to keep as reference, they are sometimes placed in special packaging (such as a photocopy of the real record sleeve) and given out to friends or devoted fans.
First pressings of original commercial releases usually have higher values among collectors than later pressings. Also collectible are 45s with picture sleeves, and original editions of LPs (and other formats) which often have inserts and other features not on subsequent editions, or tracks or cover art later withdrawn or altered. Subsequent pressings often have the same label and catalog number but can be differentiated from the first pressings by the cover, colour of the label, matrix numbers on the disc itself, etc.
