004 (Computers) 3/5/MUSTIE
As computing and software standards change rapidly, books on computers are seldom useful after 3 years. Some materials on the history and theory of computing may be kept for longer periods if more recent replacements are not available.

Printed bibliographies are rarely the most current or valuable resource for obtaining information. Only acquire and maintain where unique coverage is demonstrated.

An extensive professional collection is needed to support librarians and libraries throughout the state. Discard all that do not conform to current, acceptable practice.

050 (Indexes)
Print indexing has been replaced with electronic indexing for all but the most esoteric sources. Indexes covering periods prior to 2000 should be maintained. Contemporary indexes should be constantly evaluated for utility.

330 (Economics) 10/5/MUSTIE

610 (Medicine) 5/3/MUSTIE
Anatomy and Physiology change very little and can be kept longer than other health care topics. Keep only the current year plus 1 previous year (one reference, one circulating) of PDR and other prescription and over-the-counter drug directories, replacing when new editions become available.
620 (Engineering & allied operations) 10/5/MUSTIE
Many industries in the 620s are collected by Statute. Where titles have direct Maine connections they should be retained indefinitely.
630 (Agriculture) 10/5/MUSTIE
Be especially aware of trends in Maine agriculture.
635 (Horticulture) 20/5/MUSTIE
General gardening books may be useful for up to 20 years, so circulation is the main weeding criteria. Books about propagation of specific flowers or plants are considered outdated after 10 years. Pay special attention to horticulture for Maine climate zones.
640 (Home Economics) 10/5/MUSTIE
Be strict with old sewing and grooming materials in which styles change rapidly. Keep cookbooks unless little used; replace worn popular titles.
649 (Child Rearing) 10/5/MUSTIE
Keep abreast of changing trends and new theories. Replace older editions of standard works with current editions.
670 (Manufacturing) MUSTIE
Keep books on old clocks, guns, and toys since these items are often collected. Also keep works on tools, farm implements, etc. that are still used. Special emphasis is placed on Maine industries.
690 (Building Construction and Home Repair) 10/5/MUSTIE
Materials on current best practices with emphasis on weatherization, solar power and other topics of interest should be identified and retained.
Other 600's (Also Business) MUSTIE
Technology is making such rapid advances that any materials over 5 years old are to be viewed with suspicion; especially those dealing with drugs, space technology, sex education, radio, television, medicine, and office skills. [Check to see if resources contain any information of historical value.] One major exception: Repair manuals for older cars and appliances should be kept as long as such items are generally kept in your community; replace when they become filthy or worn from use.

745 (Decorative Arts) 10/5/MUSTIE
Retain basic technique books if well-illustrated; replace worn and dated materials. Keep all materials on the history of interior design that are in acceptable condition. Discard general home decorating ideas after 10 years unless the decorating style becomes established as a distinct aspect of American interior design (e.g. "Southwestern," or "high-tech"). Keep stamp and coin catalogues up-to-date. Historical treatments of ancient, foreign, and commemorative coins may be kept indefinitely, unless the focus is market valuation, then keep no more than 5 years.

Check closely for outdated techniques, and especially outdated equipment; if in doubt, check with local photography club or buffs.
790 (Recreation) 10/5/MUSTIE

910 (Geography and Travel) 10/5/MUSTIE
No more than 2 guidebooks are needed for any area or attraction outside of Maine. Standing orders for guidebooks should be set on biennial rather than annual basis with alternating series purchased.  1 copy of standard Maine guidebooks should be maintained for historical coverage.
974.1 (Maine History)
Collect one to three copies of all items identified.  1 copy should be labeled LUO.  Retain indefinitely.
B or 92 (Biography) 10/5/MUSTIE
With the exception of individuals directly associated with Maine, it is rare that more than 3 biographies per person should be needed.  Letters, journals and autobiographical series can be excepted from the total count.  For individuals best known for popular culture (e.g. actors, musicians) a single biography is often sufficient. Popular culture biographies should be weeded after 10 years or when interest has faded.  Newer biographies should replace older biographies unless the older version is written by a Maine author or is recognized as a definitive version.
