EBSCO E-Books

User Limit: There are four levels of access: unlimited concurrent user access, single user at a time, three users at a time, and non-linear. The access level is marked under public note in the full book catalog record page. The access limit can also be identified under Availability below the book title on the e-book landing page on the EBSCO platform. Below are some examples: 

  • 1-user access model title "Limited User Access (1 Copies Available)"
  • 2-7 user access model title "Limited User Access (X Copies Available)"
  • Concurrent Access model title  "Unlimited User Access"
  • Unlimited-user access model title "Unlimited User Access"

* Concurrent Access Model: Under this model, titles are not restricted to linear distribution (one patron at a time) but rather they can be lent to any number of users concurrently. There are a set number of lending days per title per year, typically up to 325 days. Lending days reset annually. The number of days used for each loan is subtracted from the total number of annual loan days available for the title. For example, if four users each trigger a five day loan for the same title, 20 days are deducted from the title’s 325 loan days. The combined number of loan days cannot exceed the annual loan days in a year.


Copying/Downloading/Printing: Depending on publisher-specified limits, up to 100 pages of an EBSCO e-book can be printed, saved, or emailed as a PDF file (per user) from within the e-book viewer. Publisher permissions (including printing, copying, saving, and emailing pages) will be listed on each e-book page on the EBSCO platform.

Printing/Copying

  • The number of pages may vary depending on individual publisher-specified limits. Some titles may not allow for printing.
  • If you have reached your printing limit, the option to print or save e-book pages will be temporarily unavailable.

Downloading

  • Before downloading, users need to install Adobe Digital Editions (free online) on their computers.
  • To download full e-books, an EBSCOhost account is required.
  • Download/checkout duration and download format is chosen by the patron. 

Returning Downloaded/Checked Out E-Books: E-books purchased under a limited user model will be unavailable for viewing or download if in use. A “Sorry, this e-book is in use” message is displayed until the item is free.

E-books Viewed Online

E-books that are being viewed online can be “closed” and made available to other users, by clicking the Result ListNew SearchBack, or Exit links in the e-book viewer.

If an E-book is left “open” in a browser window but is no longer being used, then the e-book becomes available to other users after the last user’s EBSCOhost session expires after 15 minutes of inactivity. 

Downloaded E-books

Downloaded e-books can be checked in before the end of the check out period using Adobe Digital Editions. E-books can only be checked in using the desktop version of Adobe Digital Editions. They cannot be checked in when using Adobe Digital Editions on a mobile device.

  1. Open Adobe Digital Editions on your computer.

  2. On the Library View screen of Adobe Digital Editions, hold your pointer over the e-book you would like to check in and click the arrow in the top left corner.

  3. Click Return Borrowed Item.

  4. Click the Return button to confirm you would like to return the e-book.

  5. The e-book is checked in and removed from your Library View screen and is available to other patrons

ProQuest E-Books 

User Limit: There are four levels of access: unlimited concurrent user access, single user at a time, three users at a time, and non-linear. The access level is marked under public note in the full book catalog record page. For items that we have not yet purchased (DDA titles), there is no access level listed on the full book record page. A book's user limit can also be identified under Availability below the book title on the e-book landing page on the ProQuest E-Book Central platform. Below are examples: 

  • 1-user access model title "Your institution has access to 1 copy of this book"
  • 3-user access model title "Your institution has access to 3 copies of this book"
  • Non-linear access model title  "Your institution has access to multiple copies of this book"
  • Unlimited-user access model title "Your institution has unlimited access to this book"

* Non-Linear Access Model: Under this model, titles are not restricted to linear distribution (one patron at a time) but rather they can be lent to any number of users concurrently. There are a set number of lending days per title per year, typically up to 325 days. Lending days reset annually. The number of days used for each loan is subtracted from the total number of annual loan days available for the title. For example, if four users each trigger a five day loan for the same title, 20 days are deducted from the title’s 325 loan days. The combined number of loan days cannot exceed the annual loan days in a year.


Copy/Downloading/Printing: User account is required. Limits are shown on each e-book's landing page on the ProQuest platform. These limits reset after 24 hours. Some publishers have set different copy/print/download limits than the defaults listed here and some books do not allow users to copy, print, or download at all. For a user signed in to an ProQuest E-Book Central account, the default limits within ProQuest E-Book Central are:

            Copying

  • Number of pages from which text can be copied = 20% of a book's total pages
  • Multiple selections copied from the same page count as just one copy.
  • Example: for a 200-page book, you can copy text from up to 40 pages every 24 hours.

            Downloading/Printing

  • Chapters in PDF, a range of pages, and the whole book can be downloaded.
  • Before downloading, users need to install Adobe Digital Editions (free online) on their computers.
  • Number of pages that can be printed or page/chapter-downloaded = 40% of a book's total pages
  • Both "Print to PDF" and "Chapter Download" deduct against the same total.
  • Example: for a 200-page book, you can print or page/chapter-download up to 80 pages every 24 hours.

Checking Out/Downloading Entire E-Books: The number of days an e-book can be checked out varies and depends on the book and the user limit on the book. Some publishers do not allow full e-book downloads.

  • single user e-books: available for 1 day checkout
  • three user e-books: available for 1,2,3,4 day checkout
  • unlimited, non-linear, and subscription user e-books: available for a variety of checkout days. Patrons can choose at the point of check out. 

Returning E-Books: Downloaded and loaned e-books expire automatically at the end of a loan, and cannot be returned early. Deleting the e-book file from Adobe Digital Editions deletes the e-book file from your device, but does not end the loan.  
 
Downloaded and loaned e-books appear in your E-book Central Bookshelf, in the “Downloads and Loans” folder, for the duration of the loan or download period. The exact date and time the loan expires will be displayed in orange.

A session will timeout automatically if left idle for 15 minutes.
