provide direct links to the web page(s) of a source
if you are unable to link directly to the source, provide the most direct link possible, and include instructions to assist the user in locating the information (as in the case of a library's online catalog)
for print or subscription sources, follow the Licensed Print and Electronic Resources policy and make sure you cite information such as title, publisher, date, etc. (See if you can find the user’s library online and offer a link to this, but be cautious about "deep linking" to a library's catalog, as these often time out and become dead links.)
Briefly state why a source was selected. Explain how you evaluated it, why it is particularly useful, or why you chose it out of all that was available. This helps the user understand your process and your selection choices. Evaluating your choices is essential; having the ability to communicate why these sources are the best for this user's question helps to promote information literacy and demonstrate your expertise.
