Tips on presentation
Your work must be typed.
Spelling, punctuation and grammar must be perfect. Be consistent in your choice of variant spellings, capitalisation, sub-headings, directions, footnotes etc.
Use double spacing, a full empty line of empty space between every line of text, and allow generous margins. This is preferred practice since it allows an editor to make notes easily on your text.
Number each page and include a front sheet with the title, your name and address and the number of words in the document.
Contact the agent or publisher and ask them about their submission requirements. If you have written a book, it is common practice to just send the first couple of chapters and a synopsis.
