Thanks for the question, and it's a good one. You've got 4 options:
1. Open Access
You can make it publicly accessible, which means the full-text is available for anyone to find and download. This what I normally suggest to people.
2. Campus Only Access
You can make the thesis available for people to download, but only if they have a current Dominican ID and password or accessing your thesis via one of the two public computers that we have in the Library. Everyone can see the thesis metadata but not everyone will have access to the full-text.
3. Open Access or Campus Only Access with an Embargo
An embargo is a timed release of your thesis. When uploading your thesis you can choose to put a 1, 1.5, 2, or 3 year embargo on it, which means everyone can see the thesis metadata (i.e. information about your thesis: Title, Author, Abstract) but no one will have access to it until the embargo is ends.
4. Closed Access
Everyone can see the thesis metadata, but no one will have access to the full-text version of your thesis except for the repository administrator.
You can choose either Option 1 or Option 2 and whether to include an embargo when you are uploading your thesis. On the online form you'll fill out for your thesis you can choose either Senior Thesis (i.e. Open Access) or Senior Thesis (Campus Only Access).
If you want Option 4, then you need to send an email request to the Dominican Scholar Administrator
