How to Read an eBook?
The way to access an e-book can be different depending on the platform the book is located. Some platforms allow you to download the whole book in PDF with one click, while some allow downloading a limited number of pages per day due to copyright restrictions.
Here are a few commonly seen examples from e-book databases:
⦿ Full book download allowed. Usually, books directly offered by publishers offer full book or chapter download options.
⦿ Limited no. of pages download per day. Two major e-book providers - ProQuest and EBSCOhost- offer this option. Note that some popular books may only allow online reading. There is no limitation if you read the book online. More details can be seen on ProQest Ebook Central and EBSCOhost eBook Collection database pages.
Other than downloading a limited no. of pages to PDF, you may also "Borrow" the whole book for a specified no. of days and read it offline after installing the Adobe Digital Editions app.
⦿ PDF full download is not available. Usually, textbook providers offer this option.
You can check out the books and read them online for a specified no. of hours.

How to Read a Call Number?
Each physical item is labeled with a call number, which contains both letters and numbers representing the source's location in the library, e.g., TX911 .V33 2019. Books on the same subject will be placed in the same range on bookshelves. When you search a print book through OneSearch, you will get a call number, which tells you where you can find the book.
