Formaldehyde is a common constituent in some cold glues used in Bindery operations today but in very tiny quantities (typically well below 0.1%). Formaldehyde constituent levels below 0.1% can be ignored in TRI calculations. (Perhaps some printers over reported?) I'm not sure if the formaldehyde is a preservative or a manufacturing by-product. A glue manufacturer (such as H.B. Fuller; http://www.hbfuller.com/ could be contacted to clarify that. It's also possible that in years past the quantities were above the 0.1% reporting threshold which could warrant emissions reporting (if over 25,000/10,000 LBS formaldehyde was processed/used). But at a 0.1% level it would take a lot of glue (10 million LBS used annually) to hit the 10,000 LB formaldehyde reporting threshold.
