(1) IR costs per item: What is the part of annual expenditures related to one item?This corresponds to the “cost per article” metrics for serials. Examples following Willinsky (2006) and recent data as shown above: Usages : nouveaux indicateurs retour sur investissement (1) IR costs per item* (2) Cost per item request* (3) Item requests per collection* (4) IR costs per user (5) IR costs per depositing author (6) IR items per scientific output* * aussi par rapport à la littérature grise CERIST Table 5: Item requests per collection (examples) (*Malotaux, 2009; ** Merceur, 2007). The interest in this indicator is that it allows for comparison of usage of different document types (here grey literature vs. published articles), laboratories etc., depending on the particular structure and metadata of an IR. It provides elements for the assessment of interest and usage of specific sections of the IR. (4) IR costs per user: What is the part of annual expenditures related to an individual user? This links the overall expenditures to the number of users. This measure requires an analysis of the log files and would provide an additional element to the assessment of impact, popularity, and readership. There is no valid data for the IR with cost information. (5) IR costs per depositing author: What is the part of annual expenditures related to an individual depositing author? This links the overall expenditures to the number of users in terms of depositing authors; and this requires an analysis of metadata and would provide information about the acceptance and use in the institution. No valid data is available. (6) IR items per scientific output: What
Probable • 1. Grey literature will not disappear. • 2. The borderline between “grey” and “white” (commercial) literature will become increasingly indistinct. • 3. The proportion of “grey” documents published on the Web will continue to increase. • 4. The Internet will encourage a greater diversity in the types of “grey” resources available (raw research results, notes and personal comments, lectures, newsletters, product catalogs, etc.). CERIST
Probable aussi • 5. Bibliographic control of grey literature will remain problematic. • 6. Open archives will offer more appropriate services and functions for at least some segments of grey literature. • 7. Some organizations – especially in the public sector but also in the private sector (e.g. Elsevier, Google, etc.) – will develop tools and services to aid in the efficient exploitation of grey resources on the Web. CERIST
Improbable • 8. Searching and collecting grey literature will become as straightforward as it is for journals and books in the traditional publishing sector. • 9. New tools for collecting, depositing, and archiving will make grey literature less ephemeral and volatile than in the past. CERIST
