warfare  areas,  such  as  Undersea  Warfare  or Amphibious  Warfare  are  also  provided.  The  Master Publications  Allowance  List  is  available  from  the  Naval Oceanographic Office on CD-ROM. It can also be downloaded via the Secure Internet Protocol Routing Network (SIPRNET). Useful Publications Useful publications include those publications that, although  useful,  are  not  required  for  inspection purposes. These publications include climatology studies,  National  Weather  Service  publications,  and certain   classified   publications.   Appendix   III   of NAVMETOCCOMINST   3140.1,   U.S.   Navy Oceanographic and Meteorological Support System Manual,   lists   several   pertinent   references   for oceanographic and meteorological support. These consist of different instructions and publications that contain information especially useful for different METOC-related tasks. However, the appendix stresses that the list is not a list of required publications. Unclassified   Naval   Oceanographic   Office publications are listed in the NAVOCEANO RP-50, Catalog of Naval Oceanographic Office Publications. Classified  Naval  Oceanographic  Office  publications are listed in the NAVOCEANO RP-51(S), Catalog of Classified  Naval  Oceanographic  Office  Publications. Source listings for NAVAIR publications, airfield summaries,  and  observation  summaries  are  discussed  in the following text. Climatic Publications The National Weather Service, the Air Force, and the Navy all produce various types of climatic studies and climatic summaries. Many of these products are routinely  distributed  to  your  command  via  CD-ROM  as they are produced. Some products must be specially ordered. The best place to find out what type of climatic information  is  available  for  a  specific  location  or  region is the Fleet Numerical Meteorology and Oceanography Detachment  (FNMOD),  Asheville  Internet  website  at: http://waves.ncdc.noaa.gov.   This   site   contains information on climatic reference publications and studies available on CD-ROM as well as in book form. It also provides a listing of several climatic studies that are currently available for issue on different types of media-paper,  microfiche,  microfilm,  or  compact  disk. It does not list any classified studies that may have been made for any particular location. The FNMOD website also provides a listing of available Worldwide Airfield Summaries   (WWAS)   and   Summary   of   Synoptic Meteorological  Observations  (SSMOs). MAINTENANCE OF PUBLICATIONS So far, we have discussed several sources that list publications that may be found in your office. Now we will discuss how to take care of the publications that you have. The   Naval   Meteorology   and   Oceanography Command centers and facilities may have rooms that are designated as a library, but for most detachments and ships, this is a luxury because of space limitations. Undoubtedly,  you  have  some  bookcase  space  available, whether aboard ship, in a detachment, or at a center or facility.  If  your  command  has  an  established  system  for filing and retrieving publications, and the system generally works, then the best thing you can do is to learn that system and work with it. If no workable system has been established, the simplest system for office-size book collections is the alphabetical filing system. File the publications on shelves in alphabetical order by the title. A computer listing (or index cards) should be made up for each book,  listing  the  title,  publication  number,  and subject(s)  covered. For slightly larger collections of publications, you may wish to divide the bookcase shelves into sections for each series of publications, such as NAVAIR publications (all publications with NAVAIR numbers), National  Weather  Service  publications,  Naval Oceanographic   Office   publications,   Naval Environmental   Prediction   Research   Facility publications,  and  so  forth.  Publications  within  each group may be arranged alphabetically. The same type of title and subject computer listing (or index card listing) may be maintained, but each entry should also include a listing  of  the  bookcase  section  in  which  the  publication is located. Your title index and subject index are the key to your library. Keep the index current. Let the other people you work with know how the publications are arranged and how the index is maintained. If the index is maintained on the office computer, let them know how to access the information, or be available to access the information for them. Some sort of checkout system or log must be used to keep track of publications that are removed from the area. The most useful reference publications, if not controlled properly, tend to "disappear" from libraries. 3-10
