Don't do this

Don't write a new book about the Lost Order before having read Tim Reese.

Don't write about the Maryland Campaign not having read Joe Harsh.

Don't give us a page-and-a-half bibliography with the OR and B&L as your only primary sources.

Think twice before proudly listing Carl Sandburg in your bibliography.

Read more, much more, if all your secondary sources (except for five of them) are thirty years old or older.

Tell your cheapskate publisher to hire an editor to advise authors so you don't have to get tips like this from some blogger on the Internet.

Otherwise, your pointless, ignorant noise is going to do more harm than good.
