I found an error/typo/formatting issue in my thesis. What do I do? Can I correct it?

The short answer is "no" so—accordingly—please take great care when proofreading, reviewing, and editing your thesis.

Changes cannot be made to your thesis after your supervisor "signs-off" on your thesis/revisions or after you have submitted your thesis to the Library.  Changes may only be made to selected pages that the Thesis Office has requested from you. 

If however, after submitting to the library, you find significant error that you feel must be changed:

1. first talk to your Senior Supervisor and,
2. with justification for such changes, he or she may write to the Associate Dean of Graduate Studies (Peter Liljedahl) office for authorization. 

If the change is deemed significant, the DGS will reply authorizing the changes and cc'ing the Assistant for Theses--and only the affected pages may be changed. 

In other words, if it is only a few errors on intermittent pages, these pages can be resubmitted.  If the whole thesis has been affected, then substitution of the complete thesis must also be authorized.
