I have been asked to try and find out how other institutions charge for services provided.
 
Our Admin Rules require us to charge $1.25 per letter size page for photocopying and mailing, or $2.50 per page for FAXing.  Technically this is for library card holders only, as the Rules specify charging the fees to the requestor's library card.  We also have a $60/hour Custom Research fee, which is not specifically defined. 
 
I just received a request from a university professor from another state, requesting copies of more than 20 articles from our local papers, so the question was:  Is this simply retrieval and copying, or does the number of copies requested in one letter make this more of a research type request.  Based on the time estimate to find the cited articles and copy them, the Research fee was favorably considered, but then we decided to go with a straight retrieval and copying fee.
 
But this brought up the question of how other libraries handle these requests, and if you do have an hourly charge for research, how do you keep track of the time spent fulfilling the request?   What time does the research start, and when does it end?  When the last copy comes out, or when all the administrative paperwork is completed?
 
Individual responses to me directly at: charlesk@librarieshawaii.org are fine, since this is just for in-house discussion.  I will keep all responders anonymous for these discussion purposes.
