I recently received a query and pages from a writer who tried to be helpful.
This is a sure sign of impending error, and yes indeed, the writer obliged.
S/he "helpfully" included links to explain or illustrate items or places mentioned in the manuscript.
Because s/he'd send a vast swath of text with NO WHITE SPACE, I'd cut and pasted the pages from my email into a word document. And of course that meant the live links clicked me over to my web browsers if my mouse accidentally came anywhere near it.
Please please please do not try to be helpful.
You have no idea what I know about or don't know about. If I don't know what billabong means, I google. On the other hand I do know where Boring, Oregon is (and that it's a real town) so it's a trifle annoying to see you think I don't.
And one other thing: nothing jerks you out of the story line quicker than your browser opening up to a page you didn't think you clicked on. The first time it happens you're pretty sure you're being attacked by gremlins.
If you absolutely must explain something, do it the old fashioned way: footnotes.
And just a reminder: a lot of links in a query often send your query to spam. You don't want to be lodged in the caw of Priscilla, you really don't.
When in doubt: follow the damn directions.
