Blue Note made the switch to 12" albums late in 1955. The Modern Jazz Series (see the 5000 series below) continued with the following 12" LPs. Many of these were issued in both monaural versions (BLP series) and stereo versions (BST 81500 series), sometimes in electronically rechanneled stereo. In certain cases, the stereo versions of recordings from 1957 onwards only appeared many years later. Beginning in 1956 with BLP 1509, Reid Miles designed most of the Blue Note LP covers. The 1500 series has been systematically reissued by Toshiba-EMI in Japan ("Blue Note Works 1500" series, 20-bit 88.2 kHz CDs); the catalog numbers are TOCJ-1501, etc. In addition, originally unissued material from these dates was made available of Toshiba's 1600 series (20-bit 88.2 kHz CDs).
