A Book Used a Few Days a Year, Historically Shared Rather Than Owned

A machzor is printed and bound the same way a siddur is, but its use pattern historically shaped its production differently, since it is opened only on the High Holidays rather than daily, medieval and early modern communities more often owned a smaller number of communal copies than one per household, with worshippers sharing books during the small number of days each year the machzor was needed.

Illumination as a distinguishing feature

Because a machzor received comparatively rare but concentrated use, several of the most lavishly illuminated medieval Hebrew manuscripts to survive are machzorim rather than everyday siddurim, the Worms Machzor and the Rothschild Machzor among the best documented examples, decorated by artists commissioned specifically for a book the whole congregation would see used together rather than a private daily object.

Modern production and disposal

Modern machzorim are mass printed like any other prayer book, produced by publishers serving each denominational and regional tradition, and there is no restriction on who may print or own one. A worn machzor follows the same disposal custom as a siddur, retired to a genizah and eventually buried rather than thrown away, since it carries the same sacred text despite its more occasional use.
