History
The full name was initially “Panton, nakladatelství Svazu československých skladatelů” (“Panton, the publishing house of the Czechoslovak Composers Association”), later “Panton, vydavatelství Českého hudebního fondu” (“Panton, the publishing company of the Czech Music Fund”). From 1967 until ca. 2000, Panton as a record label was releasing domestic recordings of all genres: classical music, pop, rock, jazz, folk, brass music, or spoken word. Particularly noteworthy is the Mini jazz klub series of forty-five 7" EPs, released between 1976 and 1986.
Today the complete Panton catalogue is part of Supraphon a.s.

Catalog numbers
The primary catalog number is always on the center labels, not on the cover. For example, earlier releases had both the mono and the stereo catalog# printed on the cover, and the same cover artwork was used for both versions. On the other hand, later represses may have had an updated numbering scheme printed on the cover, but still the original number on the labels.
—> How to: If there are both mono/stereo numbers on the cover, use only the actual one as found on the center labels and add the other one to the notes.
If the numbering scheme on cover and label differs, use the label as the primary catalog# and the cover as the secondary catalog# (see paragraph 4.8.4. of the guidelines).
For mono releases, please always add “Mono” to the format. For stereo releases, always add “Stereo” if a mono version obviously exists. But since stereo LPs were not a Czechoslovak standard until ca. 1970 and stereo 7" not until ca. 1974, you may want to include the “Stereo” tag anyway in such cases, including later represses of these records.
Catalog# schemes ca. 1967–1978:
0# #### = mono
## #### = stereo (i.e. 11 ####, 22 ####, 33 ####, 44 ####, etc.)
Catalog# schemes ca. 1978–1987:
80## #### = mono (if any)
81## #### = stereo
Catalog# schemes after 1987:
81 ####-# ### —> the last three digits were often “boxed” on the cover: [#|#|#]

Retail price code suffix
The catalog number on the cover may have a retail price code suffix attached to it, for example “11 1234 H”. However, the suffix has been used very inconsequently and is not a part of the actual catalog number. Often the actual retail price was instead printed on the cover or on the center labels.
—> How to: Please do not include the price code suffix or the retail price with the actual catalog number. If present, you should add it to the release notes though.

ZB = Kčs 60,– (12" LP)
ZD = Kčs 80,– (12" LP)
ZN = Kčs 120,– (12" LP)

Manufacturing date code
Most Czechoslovak vinyl records pressed between ca. 1967 and 1992 include a three-digit code on the side A center label: ## # The first two digits represent the year, the third digit the half-year of the pressing. For example, a record with code “75 2” on the label has been manufactured in the 2nd half of 1975.
Even if the manufacturing date differs from the sound recording copyright (℗ year), it doesn’t necessarily mean that a record is a re-press. Some releases might have been held back for up to a few years for bureaucratic or political reasons, and the code simply denotes the time window when a vinyl left the manufacturing plant.
First pressings manufactured ca. 1969–1974 sometimes didn’t contain the manufacturing date code at all, in favor of the total duration time for each vinyl side.
Represses are usually identical to the original releases, apart from this code on the label as well as different stamper codes. (Some later represses may have an updated catalog# scheme on the cover though, see above.)
—> How to: Before you submit a record as a unique release based on the manufacturing date code, please first check all previously submitted versions of the same release. Many submitters don’t include the manufacturing date code at all. In case of doubt please contact them in order to avoid duplicates. Note that in most cases, represses are not “reissues”. Only add the “Repress” format tag if you are sure that you own one, and include the original sound recording copyright ℗ year in the release notes.
