Library Classification Scheme

The Library & Information Centre operates an in-house classification scheme. The sixteen main classifications and the 228 sub-classifications are listed below to give you an idea of the breadth of information available.

Finding a Book

The letter is followed by a number denoted the sub-category followed by the initial three letters of the author’s name. For example, The Gaff Rig Handbook by John Leather is found at C5 LEA
C                     Ship Building
C5                   Rigs and Rigging
LEA                 Leather, John

 The cruise planning/pilotage section uses a slightly different system. The main classification letter for this section is Q which is followed by a code for the area (e.g. BAL for Baltic) and then the three letter author’s name.

Finding the right chart

The Admiralty (UK Hydrographic Office) charts are divided into 29 folios covering different geographical areas.  Index books define the folios areas, and lists charts by originating country and chart number, and within folios.  This makes finding the required chart straightforward.  Charts are filed in ascending numerical order by Folio, then by Consecutive number and each one is labelled with its numbers
e.g. Folio 18, Chart 603:

(Middle corner of the chart)
3894 Saaristomeri – SW Part
18 – 603

Charts can be located either in the Chart Index (thick white world atlas with numbers on different areas) or the Chart Folio Index by Area (ring-bound booklet). The Index also includes Imray and non-UK originated charts which are stored in three separate drawers. If in doubt, please ask the Information Officer.

Charts are not corrected and intended only for passage planning and for determining which charts are needed for a passage.  Parallel rulers and dividers are available.  By agreement with the Hydrographic Office, charts are not available for loan and may not be photocopied in part or whole.
