NIST SP 175A & 175B Cryptographic Standards in the Federal Government : Combined (Paperback)

Why buy a book you can download for free? First you gotta find it and make sure it's the latest version, not always easy.

Then you gotta print it using a network printer you share with 100 other people - and its outta paper - and the toner is low (take out the toner cartridge, shake it, then put it back).

If it's just 10 pages, no problem, but if it's a 250-page book, you will need to punch 3 holes in all those pages and put it in a 3-ring binder.

Takes at least an hour.

An engineer that's paid $75 an hour has to do this himself (who has assistant's anymore?).

If you are paid more than $10 an hour and use an ink jet printer, buying this book will save you money.
