Two works issued together without a collective title
Two works issued together without a collective title is a somewhat regular occurrence for children's books; much less so for adult books. The most common presentation for children's books is the tête-bêche format: two stories bound together such that a reader starts from the "front" cover and follows a story to the middle of the book, at which point the reader flips the book upside down and starts the other story from the "back" cover.
This situation is chiefly governed by AACR2R 1.1G.
If there are two title pages, determine which title is first by the title indicated first on the spine; or if there is no spine title, choose the title page or cover that does not have a bar code or an ISBN with it.
Separate the titles with a semicolon if both are by the same author.

If the works have not been previously published separately, the second title should be traced in a 246 field.

If each section has separate page numeration or if the works are bound back to back, the physical description will contain the pagination of the first work followed by a comma, then the pagination of the second work.

Notes and form headings
An explanatory note and form heading is needed if the second work is on inverted pages. This wording allows these works to be easily retrievable either by the standard terminology or by the most common variants.

An explanatory note is needed if the second work is not inverted but rather shares an internal "cover" so that both sides share the same "up" direction. (There is no form heading for this style of binding.)
