Dear Colleagues,

The Acquisition & Collection Development Section is proud to announce the publication of the IFLA Electronic Resource Guide.

The purpose of this Guide is to help develop an awareness of the key issues that every library will need to consider and address in developing an e-portfolio. 

You'll be able to read this document at the following address:http://www.ifla.org/en/publications/ifla-electronic-resource-guide 

Have a good read!
