Manuscript Critique
This service provides feedback on textual formatting and overall visual formatting, copy editing, word choice/tone, how to strengthen weak areas, and gives customized feedback based on genre.

Substantive Editing
Examines the content and structure of the manuscript as a whole. Can involve reordering large sections of text, removing text, adding text, and even rewriting.

Copy Editing
Checks for errors in grammar and mechanics/ punctuation, spelling, diction, internal/stylistic consistency, cross-referencing, labeling, and so on.

Proofreading
Final review of a fully formatted and typeset manuscript. Looks for odd spelling mistakes and hyphenation errors that may have been missed in copy editing--often when a spellchecker cannot identify specific variances--or errors that may have occurred in the layout process.
