Conferencia realizado del 12 al 14 de setiembre en Lima, Peru del 2012 en el marco del 15º Simposio Internacional de Tesis y Disertaciones Electrónicas (ETD 2012). Evento aupiciado por la Universidad Nacional Mayor de San Marcos (UNMSM) y la Universidad Peruana de Ciencias Aplicadas (UPC). / The NDLTD Union Catalog is an international collection of ETD metadata that is
harvested from various institutional, regional and cross-institutional collections. The
Union Catalog has grown substantially in the 10 years since its launch and now
contains almost 2 million records. However, various issues have surfaced during the
maintenance of the Union Catalog and its downstream service providers. For
example, at this scale, the well-known best practice of the OAI-PMH to restrict the
size of a response to 100 records or 1MB has a severe impact on harvesting time.
This paper describes this problem and other issues that are relevant to the Union
Catalog and similar projects. For each such issue, solutions are discussed. Together
these present a set of guidelines not only for large union catalogues but also for the
design of large digital library collections in general.
