----------------------------Original message---------------------------- Paige, Jim, Johnny, and Map Catalogers: This is a fate which, I believe, is faced by catalogers of ALL types of materials, with a possible exception of Rare Materials. It is one of the main reasons my involvement is with computer systems and not with maps -- "they ain't no work out here nowhere what I can get". A word of caution regarding the retrospective conversion. Without piece in hand, the accuracy of retrospective conversion depends on the quality of the information you send them. Be sure you define carefully the acceptable error rate. And find out what happens to those things they can't identify. It seems many companies deal with the part of the collection which is fastest (i.e. easiest) to convert. BUT you are left with the hard part (i.e. slow and expensive). A study I did about a year and a half ago showed that our in-house conversion rate (taking into account all factors including computer down-time) was a little less than 3 records an hour. An expensive process, outsourcing might be a good option if you don't have to spend too much of your time preparing the info. If you get a quote, consider your investment of that time in your cost evaluation. That is a very real but ususally ignored cost. Or are you handing your collection over to them and they return it.
