Heralds record Coats-of-Arms in books called Rolls of Arms

Coats of Arms are more than just interesting colorful symbols placed on "awesome" shields. A Coat of Arms tells us about people and families that lived hundreds of years ago. In the middle ages it was a herald's job to know which coat of arms belonged to which knight or nobleman. Heralds often kept a record of coats of arms by drawing or painting them on a roll of parchment. It sometimes stayed in the form of a roll and other times it was made into a book. This record-keeping format became known as a Roll of Arms and it generally included rows of painted shields along with the name of the person who owned the coat of arms. Roll of Arms are important primary documents that preserve information about many generations of knights and families dating back to the 1200s and are still being made by 21^st century heralds today.
