O'Reilly Media is a leading publisher of technology books, video, and conferences. Known for the 'animal book' covers on programming and tech titles.
The publication number segment following the publisher prefix is 5 digits long, giving this publisher a theoretical capacity of up to 100,000 unique ISBNs within this prefix.
The ISBN system works by dividing the 9-digit body of an ISBN (after the EAN prefix) into three parts: registration group, registrant (publisher), and publication number. Shorter publisher prefixes indicate larger publishers who need more publication numbers; longer prefixes are assigned to smaller presses with fewer titles.
