I've been on a full-requesting-spree these last few weeks, thus have noticed some things which might have escaped my attention had I seen them over a longer period of time.
None of these are deal-breakers. I'm not going to summarily reject your novel if you do/don't follow these guidelines.
My assumption is that you want to look professional and be professional.
These tips will help you.
1. Do NOT include the draft number (#1 is bad, but #100 isn't comforting either)
If you need to distinguish versions, use the date.
2. Do not list what rights are available.
There's almost no chance you'll list them correctly, plus I'm not acquiring rights; I'm signing YOU for representation.
3. Leave out the dedication, and acknowledgements.
4. Leave out any kind of copyright notice. You don't need it.
5. Double space; 1" margins; TNR or Courier font (I change everything to TNR)
6. Do NOT include links of any kind. Sometimes my computer tries to open those links while it's downloading the manuscript and confuses itself into paralyzing bewilderment.
