Nonprint selection criteria
- Formal instructiono How will it be used?
- Recreational use o Buy, not show in group, show at home nit pick, rent a movie show at home to friend
- Audience (adults, children, all ages)
- Circulate/in house
- Member resource sharing network
This is especially true for the more traditional nonprint, audio and visual. When going to acquire a book (shop, jobber, online) , get a discount for a wide variety of selection. There is a much easier paper trail. Must preview videos for their suitability before presenting. Chapters sell CDs and videos, a few educational, more commercially; few bookstores sell many AV materials. Go to distributor – they are just selling the product, not making it. Ask for a preview before committing to buy, check the suitability. Non-print materials aren’t as widely reviewed as print materials. Also rent videos if they won’t widely be used for a period of time.
