Do it the hard way; Rube Goldberg and modern times. (OCLC #111971)

This government document has a pop-up of a Rube Goldberg machine! It is a fairly simple one, similar to this noise-maker.

RDA does not specifically address pop-up or otherwise movable books, so I looked at LC’s guidelines for Toy and Moveable (T&M) books. Following those guidelines, I included a 500 note:

500 __ ǂa Includes pop-up illustration of a Rube Goldberg machine.

but as there was only only illustration like this, I did not go so far as to include the subject heading:

650 _0 ǂa Pop-up books ǂv Specimens.
