We no longer bind dissertations. If you do a search in Google on "book binding near me," you will find several options near where you live with a description of their services. Some of them are reviewed. Find one that does stitched binding/library binding. If you cannot find a suitable local printer, you can use a service that allows you to upload a file and they will ship you a bound copy.
All of these services print out a copy of your dissertation from the PDF/document you submitted and bind it.
Here are terms to look for when you search:
"Perfect binding" bound using hot glue like a paperback. Doesn't last. Decidedly not "perfect".
"Library binding" bound using stitching, reinforced covers. It lasts and may be available with different types of covers.
"Specialty binding" bound to your specifications. May involve expensive materials and be stitched by hand to achieve a specific look and feel.
