Starting with the Fall ‘24 semester, eCampus became Princeton’s coursebook provider. eCampus.com is an online bookstore for new and used books, rentals, electronic textbooks, study materials, and book buyback services. This change allows Labyrinth Books to focus on its goal of being a scholarly academic bookstore. The change also aligned with student and faculty preferences for offering course materials in alternative formats.

What are Marketplace books?
-
Marketplace books are items listed and shipped by independent sellers, such as other students and parents. These sellers have two business days after your order is placed to ship the order. Please be sure to read each item’s description before ordering, as each Marketplace book has its own condition, description and shipping cost. Not all Marketplace items are available for expedited shipping, and these items will arrive separately from the rest of the order.
-
When will my books be shipped? What is the cost of shipping?
-
The “ship to Frist Campus Center” box on the checkout page is the default address of shipping (minus Marketplace purchases). Shipping is free to the Frist Campus Center. This box can be unchecked and any valid shipping address may be entered. When the package has been shipped, you will receive an alert from eCampus.com. If you have selected a non-campus address, you will receive a delivery alert from either eCampus.com or the delivery carrier. If you selected a campus address, you will receive a notification from [email protected]. Please wait for this notification before heading to Frist for pickup. Shipping to locations other than Frist is free for packages costing $59 and more (minus Marketplace purchases). Books are shipped and delivered Monday through Friday.

- For lists with course materials from overseas, the deadline is May 2, 2025

We encourage faculty and their delegates, especially in the language departments, to get their course material adopted as soon as possible. This allows the online bookstore team adequate time to perform publisher availability checks before student ordering.
The Higher Education Opportunity Act (HEOA) has provisions to reduce costs to students while supporting instructors’ ability to select high-quality course materials. HEOA requires that course book information be made available to students before they enroll in a course. Your school complies with HEOA by asking faculty to submit course adoptions to the Online Bookstore Team so that they can be listed accordingly. This act requires that textbooks be listed as accurately as possible at the time of student registration.
Providing course adoptions to the online bookstore at https://princeton.ecampus.com prior to the deadline allows eCampus to buy back textbooks at the best prices for students at the end of the semester and offer them at a discount in the future as used or rental textbooks.
-
How do I get help with a desk copy request?
-
To request more information on desk copies, please email [email protected].
-
My course says textbooks to be determined. What does that mean?
-
Until an adoption is added to a course or the "Textbooks are not required for this course" checkbox is selected, each course will default to "Textbooks to be determined."
This allows your school to remain in HEOA compliance while informing students to check back later.
If books are added after the deadline, a course will automatically be marked as TBD for 24-48 hours.
This allows your online bookstore team time to confirm publisher availability. You will only be notified if an issue with a book exists.
-
I want to use the same book as last semester, but I cannot remember the ISBN. How do I add this book?
-
You may view past adoptions by selecting the "View Adoption History" button located under the "Course Adoption Details" bar. Simply select the "Adopt this item" box of the book you wish to add and select "Add Adoptions."
-
I would like to have a course pack or other custom learning material created; can you assist?
-
Yes. We will work with a custom publishing company to have an ISBN assigned to your course pack. Please contact your online bookstore team at [email protected] for additional instructions.
-
I tried to add a custom book, but it said the item was not in the product catalog. How do I list this book? How do I list materials that are not books?
-
If you try to add a book or product that is not in our product catalog — custom books, course packs, foreign titles,
For calculators, lab coats, clickers, etc., please contact your online bookstore team at [email protected]
We ask that you provide any information that may be helpful to assist us in adding the product to our catalog.
After the item is created, we will add it to the course on your behalf and email you confirmation once complete.
-
I already submitted my adoptions. What happens if the instructor changes?
-
Course adoptions will remain the same per course, not per instructor. Therefore, even if an instructor changes for a course, the adoption(s) submitted will remain listed for that course.
If the new instructor wishes to change adoptions after the deadline, please inform your online bookstore team at [email protected].
-
How do I remove an adoption from my course?
-
Adoptions may only be removed through the FAST adoption portal before the deadline.
To remove, select the X to the right of the book information.
To remove after the deadline, select "Request Adoption Change" within the FAST adoption portal on the book(s) in question or email your online bookstore team at [email protected].
This allows our customer service team to contact students who may have already ordered.
-
I submitted my adoption for one course, but all sections will use it. Do I have to add this to every course individually?
-
No. You may add the same adoption(s) to multiple sections. After you have added the adoption(s) to one course, select the "Copy All" button and choose the course(s) to which you wish to copy the adoption(s).
-
How can I check the price of a book before I add it to my course?
-
Prices and purchasing options may be reviewed by using the Catalog tool at the top of the FAST adoption portal. Enter the ISBN in the search bar, then select Details.
-
Where do students pick up their books? When are they shipped, and how are they delivered?
-
Students may ship to any valid shipping address. Students will receive email and text message alerts (if they choose to opt in) when their package is shipped. Books are shipped based on availability. The availability of each book will be indicated under the condition of each item during the ordering process.
