Agreed. But I think it needs to be said that you can not provide information if you are not asked.
Some years ago someone authoring a book asked me for photos and some specific information. They were not interested in roster information or dispositions in regards to the road I worked for and had fairly well documented. The book came out and I call attention to some errors. The response I got seemed to be worded so I would feel guilty because I did not provide unsolicited information.
Felt that it was sort of a cheap shot since the original request targeted specifics.
Gotta go now, got some hot stuff I just found that I have to hide until the time is right.

Speaking of errors in published works, I will bow to the need to complain about a pet peeve. Namely the tendency of what I might call a "collector of information" to withhold it from authors only later to "spring" forth with a correction when the author is published. Fortunately the STMFC is not home to such "collectors".
