The goblins Lupus summoned were from the library books that use the mercenary system. You use gold to summon them. There are plenty of monsters Ainz could summon there (monster data books were stated to be the majority in the library in volume 8), but he doesn't want to deplete his gold reserves doing so. The reason Lupus had to scrounge is because Nazarick probably wouldn't have bothered saving anything LOWER than the highest level goblins summon book.
