It was about a five year project. We separated charts by scale. 1:2-3 mil+/- are classed by continents or seas. 1:750k - 2mil +/- are classed by region, and 1:750k and larger are classed by country or U.S. state. 1:25k and larger +/- are usually harbor charts, except that a lot of large scale charts with the title "Approaches to ..." are classed as coastal charts because there is usually a larger scale harbor chart for "...". Harbor charts get G xxx1 .P55 svar. .U5 Coastal charts get G xxx2 .C6P5 svar. .U5 Charts showing an island or a major body of water get G xxx1 .P5 svar. .U5 A lot of large scale maps of harbors and ports are shown as insets on coastal charts. I classed them as harbor charts if the harbor inset comprised half or more of the sheet. A chart that covers the coast of 2 or more regions/countries/states is classed with the one that has the most coastline. If it was equal, it was classed with the next higher region, except if it had an inset, then it was classed with the one that the inset was in. Even with these guidelines, there are many judgement calls to make on individual sheets. We created index maps on photocopied pages from the DMA and NOAA chart indexes. I have created a few index maps in Adobe Illustrated format, which I can convert to .pdf or .jpg if you are interested.

We have always stored the charts as a set, with a G32301 class number. We would like to break the collection down by region (1-9) geographically, just so we don't have 1 bib record with 5000 items attached. We're making sheet lists and index maps (http://libweb.uoregon.edu/map/naut/nautical_curr.htm), but we do want barcodes and item records for inventory control. Has anyone done anything like this? What's your method (short of individual bibs and sudoc #s) for wrangling this large set? __________________________________________ Jon R.
