Herculaneum and Pompeii are two different places some distance apart. Pompeii was a serious commercial center, Herculaneum was a smaller seaside resort. The scrolls are from a buried library discovered some time ago at Herculaneum. They would have quickly burned at Pompeii.
Other scrolls have been found in Pompeii, just no libraries (so far). They didn’t get carbonized as they did in Herculaneum. The House of the Vettei was owned by a couple of freedmen (brothers, probably) and they financed their remodeling and probably small business using loans from a private banker who lived down the street. The loan records survived in the banker’s house. Not bad. :^)
