We regularly look at usage information for Iowa Research Online. The software shows us the 10 items receiving the most downloads overall (total use is averaged out across how long the item has been publicly (freely) available), which allows new items to enter the top ten. However, this list tends to remain similar from month to month (and day to day). Looking at the number of downloads for a specific month sometimes highlights different items, but typically the most used items remain similar across months.

The most used items for November were:

• Twitter Data Stream: Obama McChrystal
• Design of wind turbine tower and foundation systems: optimization approach
• Nurse manager competencies
• Three essays on the customer satisfaction-customer loyalty association
• Estructura y forma en “El poema de mío Cid.” (Hacia una explicación de la imitación poética de la historia de la epopeya castellana)

Other than the first item, they all appear on the most popular papers list.

In order to find other items that are seeing an increase in their usage, we have begun comparing the use of an item with the previous month. These items may not have had the largest use overall, but the number of downloads was quite a bit higher in November than in October.
