OpusMaximus is a collection and online catalogue of vinyl records from a personal archive built over many years. It brings together more than a thousand titles spanning classical music, opera, jazz and popular music, with rare first pressings and reissues. The collection ranges from records on the Soviet Melodiya label to releases from Deutsche Grammophon, Decca, EMI, Columbia, Philips and Supraphon.

Each listing provides practical details to help visitors identify and assess a record, including the performer, conductor and orchestra where applicable, label, country and year of release, and catalogue number. The condition of both the sleeve and the vinyl is described using the international Goldmine grading scale, with a separate guide explaining the site’s terminology and abbreviations. Visitors can browse records by genre, label, performer or composer, and view recent additions.

Orders, payment and delivery are arranged through the seller Maximus on Avito. Buyers can ask questions about individual records there and discuss collection in person. OpusMaximus also provides information about its collection, purchasing arrangements and contact options.
