Query: Excellent book

This is a great book for court reporters, scopists, proofreaders, anyone who needs help with grammar or punctuation. This book will teach you when to use a comma; semicolon; colon; capitalization; etc. This book helps with troublsome words like "legislator" or "legislature"; it helps with one word/two words; when to use a comma instead of a period after the answer "yes" or "no"; etc. This is an all around great book for anyone who uses punctuation or grammar in their everday life.This is one of the best books I have read on this subject and I highly recommend it.
