Do stores own product and pricing information?

Question

I was recently evicted from the college bookstore for collecting information about the books assigned for classes, including the isbn number the price of the books.

I publish the ISBN and price information on the Internet so students at my university can compare the price of the books with online retailers such as Amazon.

I have two questions:

1. Do stores own the copyright of product and pricing information?
2. Can any store manager evict any customer for any reason? Am I trespassing if I refuse to leave?

Thanks for your help!

Answer 1

The store does not own the copyright information, and pricing is a matter of public awareness because it is on the item.
Yes, you can be evicted from a business for any reason as long as it is not discriminatory (sex, religion, race, etc).

They were miffed that you were potentially decreasing their sales by alerting the consumer that there is other options out there.
