Concentration should be on popularly written titles and materials of interest to the informed lay-person. 370-379 Library and education journals, and publishers catalogs such as ARCO, Barron's, or Petersons are the primary selection tools. There is a standing order for VGM career materials. Primary consideration is given to keeping the collection current, but classic titles and historical studies should be retained. Many areas, such as crime, personal finance, political science, some areas of law and legal issues, tax materials, real estate, etc., can be weeded heavily each year because the materials date rapidly.
New titles are preferred rather than replacement copies.
Because law materials date rapidly, retrospective development is not feasible. Weeding must be done on a continual basis with updates and new editions purchased to replace the old titles. This area can be problematical as even old titles on such subjects as adoption, personal narratives on mental illness, addiction and other personal problems still circulate heavily. The most popular segment of the 360s is the true crime narratives of which there is prolific publication. They circulate heavily when first published but don't have the lasting circulation potential of mystery fiction.
