The theme of the 1991 Virginia Summer Reading Program combined a fascination with the world of prehistoric creatures with the excitement of discovery. The summer program offers the library an opportunity to showcase its services for the entire community and demonstrates the contribution the library makes to the development of lifelong learning. This guide contains posters, reading logs, stickers, certificates, and manuals in support of the summer reading program. Each library sets its own registration policies and rules for the program. It is anticipated that this program will appeal to children aged 3 to 12 years, although many libraries have seen, in recent years, an increase in the number of participants aged 12 to 14 years. Program features such as reading logs, incentives, and certificates are presented, with multiple illustrations that can be copied. Bibliographies include 67 books for young readers, 21 books for young adults, and 4 books for librarians; and 16 resource organizations. (SLD)
