Alexandria Books
From Memory Alpha, the free Star Trek reference.
The Alexandria Books was a bookstore owned by Henry Janeway during the late 20th century, an establishment that had been in his family for generations.
The store was located in Portage Creek, Indiana, United States of America. Its store hours were from 9am to 5:30pm.
In 2000, the bookstore was the center of some controversy as Janeway refused to sell the property, single-handedly blocking construction of the Millennium Gate. However, after some convincing from Shannon O'Donnell, Janeway ultimately made the decision to close the store with the promise that O'Donnell would try to find a place for a new bookstore within the Millennium Gate.
