I'm on vacation most of last week and next week, so I don't have a real reference question to share. Instead, I thought I'd highlight this post from last year from Lifehacker.com: Top 10 Tactics for Diagnosing and Fixing Your Sick Technology.
Just about everyone who works in a library is a de facto tech support person - whether it be for your own work station, or helping a coworker or patron. So instead of an normal reference question, hopefully this post will help in answering reference questions.
The tips they provide really run the gamut of applicability, but tips I think are most relevant are:
10. Disable Crap You Don't Need.
Helpful in the way they intend, but also relevant in patron support in terms of "focus on one aspect of the problem." For instance, if a patron says, "I can't download books from Overdrive," you have to go through a mental checklist every single time: is their computer connected to the internet, are they getting to the Overdrive catalog, are they checking out the book properly, is their any kind of block on their account, are they getting the right format for their device, etc. By ignoring extraneous details and deliberately going through the process, you can usually fairly quickly identify whatever the problem may be (fixing it, on the other hand, is a different matter).
8. Talk It Out with a Troubleshooting Buddy
This is good for any type of reference question - if you get stuck, ask a coworker. Any two people will probably approach a question differently, and someone else might think of something you haven't. Relying on colleagues is a great way to provide excellent customer service (well, provided you have excellent colleagues).
7. Make Sure It's Not Just You
I actually use downforeveryone.com frequently (and am always oddly delighted when I find someone else who does too). Patrons seem to be less upset about not being able to get into their email if you can show them that the problem seems to be with their email provider, not the library's network.
3. Use Alternative Search Engines When Looking for Help
Definitely. It's good to be come very familiar with your standard tools, but don't be locked into them. And not just search engines - remember to use the library's print resources, databases, vertical file, local resources, etc, when looking for an answer.
2. Hit Up Helpful Q&A Web Sites
I do this all the time, both for answering patron questions and IT support within the library. Patrons think up some pretty weird things, but chances are someone else on the internet has already figured that weird thing out. Look for help forums, and don't be afraid to interact on them. And tell the patron you've asked their question, just to give them a heads-up that the answer might not be immediately forthcoming. Also, any time I get a strange error code, or try to do something slightly counter-intuitive (like read Kindle books on an iPad), searching web forums is a quick way to pick the internet's collective brain. Likewise, calling other libraries, relevant organizations, or real-life experts can be a good idea, too.
This applies to so many things - from literally restarting a frozen public workstation to taking a fresh tack on a difficult problem. Turn it off and turn it back on again is the #1 suggestion for a reason - and why Roy always answers the phone that way:
