Rate as essential requirements that, if lacking, will have a highly detrimental effect on our use of or plans for the new system. Top priority features should be rated essential.

Examples of essential features are: the ability to export a bibliographic record from RLIN or OCLC and immediately load and index the record in the Orbis2 database; email circulation notices; an online shelflist that correctly parses LC and Old Yale call numbers; the ability for readers to

see their own checkout records.

IMPORTANT

Rate as important requirements we would like to have, but that if lacking, will not have a highly detrimental effect on our use of the system.

An example of an important feature is the ability to see the OPAC view of a bibliographic record from within the cataloging module rather than by executing a search in the online catalog.

DESIRABLE

Luxury criteria should be rated as desirable. Include "futuristic" features and development opportunities for the vendor in this category.

A desirable feature is the ability to run under Linux.
