eBooks in academic libraries: Pros and cons

PROS:

• PDA model is cost efficient for the library as opposed to the old model of purchasing monographs in print for "just in case."
• PDA model makes many more titles available to the patron as opposed to a print-only library collection. 
• Ordering an eBook from acquisitions is far quicker than ordering a print book.
• Take up no shelf space, a big plus when shelf space is scarce.
• Cannot be lost, damaged or stolen - this is a big cost to the library.
• Patrons can have instant access to the book, especially helpful for distance students.

CONS:

• Cannot interloan eBooks (except chapters if they can be downloaded as a PDF).
• Patrons often prefer print books - using print has obvious advantages, e.g. don't need to read off a computer screen, easy to photocopy chapters.
• DRM restrictions on printing a chapter, sharing the book, etc.
• Licensing restrictions, e.g. only 3 day loan, single user access.
• Library doesn't own the book, it only has access to it - this raises issues about digital preservation, etc.
• Can be much more expensive than the print version of a book.
