you might want to go back an re-read your networking books.
As far as "bibles" go, however, Halabi's _Internet Routing Architectures_ is the BGP variant.
TCP/IP Illustrated might not mention CIDR since it was still pretty new when those books were written. My copies haven't been opened in years so I can't be sure.
If you've performed any subnetting in the last 15 years or so, however, I fully expect that you have encountered CIDR.
The very first line has enough information to know what it does:
"A tool to enumerate CIDRs by querying RIRs & BGP ASN prefix lookups"
In other words, it queries two sources (regional Internet registries -- the organizations referred to above -- and information from the BGP protocol) to enumerate blocks of IP addresses.
