Future of DDA at AUT Plan to continue with DDA but some concerns. Steep increase in cost of STLs Accessibility of ebooks Analytics Weeding What s next
Some observations on DDA trends YBP currently manages 284 active DDA programs (92 multi-vendor). Every DDA program is unique. Repeat usage of DDA purchased titles is on average significantly higher than titles purchased using other collection development methods. Increasing trend toward multi vendor DDA. Use of Manual DDA varies enormously but is valued by many libraries. Recent publisher price increases for STLs are forcing libraries to reassess the use of STLs.

DDA questions worth asking What is the objective of your DDA program? Ownership or just in time access? How does DDA fit in with other collection development practices? Budget management challenges. What are the implications for resource allocations and tracking? How are your workflows going to change? To mediate or not to mediate?
DDA questions worth asking Weeding non purchased DDA titles. How long do you keep them, and what criteria do you use to weed? Is it worth enhancing DDA records with Tables of Contents to improve discoverability?
In conclusion The economic and technological environment of libraries is requiring librarians to seek and demand more options in purchasing models and pricing considerations. Not all collections and published material will fit into a DDA process and there is a strong argument for several collection development methodologies in order to provide a balanced and focused collection to support both teaching and research.
