Liberty tried a plethora of different series over the years, most of which lasted only a few albums. The 6000 jazz series started about the same time as the 3000 pop series in 1955, but lasted less than two years. The 9000 series was another early (1956-58) pop series. By 1956, then, Liberty had a cataloguing system that made some sense, with a 3000, a 6000, and a 9000 series.

Then, in 1958, stereo hit and all cataloguing sense went out the window. The LST-7000 series was started for stereo releases, but corresponding albums in the 3000 and 7000 series had completely different numbers. Stereo sampler albums were issued under a new LST-100 series. A series was started using the 6000/7700 series designation (the Robert Rheims religious series) that duplicated catalog numbers already used in the 6000 Jazz series. A 15000 Classical series was started in the early 1960s, as well as a 16000 Soundtrack series, but these lasted scarcely more than a mere handful of albums each. A 5000 International series may have lasted only a single album. A 5500/6600 series was started in 1962 that included a variety of "sampler" albums, as well as a couple of more-or-less regular pop issues. A special "2-LP set for the price of one" by Bud and Travis was issued on a new 11000/12000 series, both catalog numbers of which would be duplicated later by other albums.

There was also a series of promotional releases (the MM-400 series), of which we have little information at this point.
