The LP (long play), or 331⁄3rpm microgroove vinyl record, is a format for phonograph (gramophone) records, an analog sound storage medium. Introduced by Columbia Records in 1948, it was soon adopted as a new standard by the entire record industry. Apart from relatively minor refinements and the important later addition of stereophonic sound capability, it has remained the standard format for vinyl albums.
Format advantages
At the time the LP was introduced, nearly all phonograph records for home use were made of an abrasive (and therefore noisy) shellac compound, employed a much larger groove, and played at approximately 78 revolutions per minute (rpm), limiting the playing time of a 12-inch diameter record to less than five minutes per side. The new product was a 12- or 10-inch (30 or 25cm) fine-grooved disc made of vinyl and played with a smaller-tipped "microgroove" stylus at a speed of 331⁄3rpm. Each side of a 12-inch LP could play for more than 20 minutes. Only the microgroove standard was truly new, as both vinyl and the 331⁄3rpm speed had been used for special purposes for many years, as well as in one unsuccessful earlier attempt to introduce a long-playing record for home use.

Washing a dirty LP record using soap and water - cheap and safe method!
I have used this technique to clean very dirty records that I have bought from thrift stores, yard sales, and antique stores. It works very well. If you don't have reverse osmosis water on hand to rinse the washed record, you can use distilled water.

What is the difference between an EP and an LP?
LP stands for Long Play, and means, in essence, a full album. The term began being used to refer to 12-inch 33 1/3 RPM records that have a runtime of about 30-44 minutes, and, over time, the term also started to be used with cassettes and CDs.
EP stands for extended play, which is longer than a single and not long enough to be an album.
The exact requirements are not necessarily set in stone. Different sources will give different definitions.
For sales purposes, the Recording Industry Association of America says between 3 and 5 songs, and a runtime under 30 minutes is an EP. But for Grammy Awards, an album must have five or more songs, and a runtime over 15 minutes, and they do not differentiate between LPs and EPs.
On the other hand, both Apple Music and Spotify use the criteria of 4 to 6 songs with a total runtime of under 30 minutes. Apple Music also considers a record an EP if there are 1 to 3 songs, with one song longer than 10 minutes, and a total runtime of less than 30 minutes.
But do the exact terms matter? Not really. Other than streaming services putting the album in the EP section of an artist's profile, there's no real practical difference between an album being called an EP or a LP.
Thanks for watching.

#vinylcollector #vinylrecords #vinylcollection
The LP (long play), or 331⁄3rpm microgroove vinyl record, is a format for phonograph (gramophone) records, an analog sound storage medium. Introduced by Columbia Records in 1948, it was soon adopted as a new standard by the entire record industry. Apart from relatively minor refinements and the important later addition of stereophonic sound capability, it has remained the standard format for vinyl albums.
Format advantages
At the time the LP was introduced, nearly all phonograph records for home use were made of an abrasive (and therefore noisy) shellac compound, employed a much larger groove, and played at approximately 78 revolutions per minute (rpm), limiting the playing time of a 12-inch diameter record to less than five minutes per side. The new product was a 12- or 10-inch (30 or 25cm) fine-grooved disc made of vinyl and played with a smaller-tipped "microgroove" stylus at a speed of 331⁄3rpm. Each side of a 12-inch LP could play for more than 20 minutes. Only the microgroove standard was truly new, as both vinyl and the 331⁄3rpm speed had been used for special purposes for many years, as well as in one unsuccessful earlier attempt to introduce a long-playing record for home use.
