PolyGram Record Service B.V., Baarn. Operating under this name from ca. 1980 until 28 January 1993.
Dutch company with lacquer cutting, vinyl plating and pressing, cassette duplication and printing facilities.

Previously called:
Phonodisc B.V. (1962 - ca. end of 1979).

Here belong all editions that carry an embossed "PRS Baarn" stamp on the back cover and/or a 670 in the matrix.
The embossed stamp means the record was also printed/assembled at PRS Baarn - please use Printed By.
A stamped 670 in the matrix means the lacquer was cut at PRS Baarn - please use Lacquer Cut At.

PRS was a full service provider for the Benelux markets but also a backup plant for other countries.
Pressed can be added only under the following circumstances:
1. Paper labels with elevated pressing rings at the label edge, AND
2. English centre label copyright rim text.
Additionally, but not always:
3. Made in Holland on centre labels,
4. STEMRA or BIEM STEMRA as rights society.
When in doubt or with differences (e.g. German copyright text, GEMA, other matrix numbers), do not add pressed by as credit.

1Y / 2Y etc. in the matrix is a format identifier, originally invented by Philips.
E after the side identifier (1/2) stands for 7" EP 45 RPM Stereo.
F after the side identifier (1/2) stands for 7" 45 RPM Mono.
L after the side identifier (1/2) stands for 12" 33 1/3 RPM Mono.
M after the side identifier (1/2) stands for 12" EP 45 RPM Stereo.

Usually, there also are specific extra stamps in a format such as: "111" or "11 4". These are present much lighter than the other data in the runouts and are often not ordered very well. These numbers indicate the Father, Mother, Stamper numbers.
