Dual systems will be synchronized most of the time. Staff may find this advantageous because it will require fewer changes to daily workflow in the short term. There will be a slower transition and longer learning curve for staff. Allows staff to select preferred workflow based on diverse situations and varying technical capabilities. Offering the potential to use dual systems may be easier to sell to the existing library community and may be more acceptable to members in the short term.
Dual systems are inefficient.
Adoption of ILL management systems may be slower if use of dual systems is facilitated. Will create a burden on ILL management system vendors. This could be viewed as a provincial American decision and may indicate a lack of regard on the part of OCLC for the international market and international standards. Changing the standards with these extensions may increase difficulty in expanding efficient ILL practices beyond North America. May transmit a message that OCLC is not interested in market penetration and expanding access to cataloging.
