IBM BOOK format
IBM BookManager Softcopy is IBM's legacy online documentation system, created in the 1980s. It was historically used mostly on mainframes, midrange (AS/400) and OS/2, although it also saw some use in other areas including AIX.
IBM no longer uses it for new documentations of its products, but there is an immense quantity of legacy electronic documentation from the period when IBM actively used it (from the 1980s thru 2010s), particularly documentation CD-ROMs/DVD-ROMs and images thereof.
The file-internal style (?) format apparently is called IBMIDDOC.
The standard DOS style extension is BOO, and "application/book" is sometimes used as MIME type, but was never officially registered.
Internal structure
The internal structure is fully documented as a part of the Geist reference implementation on GitHub.
