Bibles

I fear that buying two more old Bibles at Sunday's car boot sale means I now have a collection of Bibles.

According to www.dictionary.com a collection is "several things grouped together ".
The definition for "several" yields "Being of a number more than two or three but not many"
and finally, the definition of "many" is "Amounting to or consisting of a large indefinite number"

So, what have we learned? A collection is more than two or three things, but not as much as a large indefinite number. Thanks for that.
