In light of the COVID-19 pandemic, ºÚÁϲ»´òìÈ Libraries has modified several policies and services for the upcoming semester to ensure the safety of library employees, students and faculty.
Adjustments have been made in accordance with recommendations and research provided by , the ²¹²Ô»åÌý on how long the COVID-19 virus survives on materials that are prevalent in libraries, archives and museums. The  draws on authoritative, science-based information and research to inform how materials should be handled to mitigate exposure to COVID-19.
ºÚÁϲ»´òìÈ Libraries is using the results of the REALM research to guide its practices for the year. For example, beginning in the Fall 2020 semester the Libraries will shift from print reserves to electronic reserves; this is in response to the typically fast turnaround between borrower interaction with physical reserve items. Another modification: the Libraries has implemented a quarantine period of 72 to 96 hours for all materials after they have been touched.
In March, the Libraries began quarantining items per national CDC guidelines and began using UV light sanitizers for items whose entire surface could be sanitized, such as keys and equipment. The Libraries has incorporated quarantining into all workflows that involved touching books or other library items.
Library items are sanitized using UV light.
The Libraries is also requiring that any items touched on the shelves in the Libraries facilities be returned to designated shelving carts to ensure the items are adequately quarantined before being reshelved.
These measures and future policies implemented by the Libraries are intended to ensure the safety of employees and users and the protection of valuable collection items, while continuing to provide access to the resources and services that the campus community relies on.
Background on the REALM project
The REALM project involves multiple research tests conducted by Battelle, the world’s largest independent nonprofit research and development organization. Test 1 research results, made available on June 22, focused on how long some commonly circulated library materials would need to be quarantined prior to being returned to public circulation. Testing was conducted by applying the virus that causes COVID-19 on five materials held at standard room temperature and humidity conditions. The materials tested included hardback book cover, softback book cover, plain paper pages inside a closed book, plastic book covering and DVD case. The items were not stacked. Results showed that the virus was not detectable on the materials after three days (72 hours) of quarantine.
Test 2 research results, released on July 20, included testing the COVID-19 virus on braille paper pages, glossy paper pages, magazine pages, children’s board book and archival folders. Samples from each item were inoculated and placed inside the closed book or magazine. The items were then configured to mimic common storage conditions such as stacked or shelved books, or a pile of folders or magazines. Results show that after two days of quarantine in a stacked configuration, the virus was not detectable on the archival folders. After four days of quarantine in their stacked configuration, the virus was not detectable on the braille pages, glossy book pages and board book. The magazine pages showed a ³Ù°ù²¹³¦±ðÌýamount of virus at four days. Day Four was the final timepoint tested. Compared to the results of Test 1, the results of Test 2 indicate that a slightly longer quarantine time for some types of cellulose-based paper materials sitting in a stacked configuration may be required to render COVID-19 undetectable.
Battelle began testing a third round of materials on July 10. Items being tested include DVD/CD, talking book USB cassettes, acrylic display cases, storage bags and storage containers. The results of examining plastic-based materials in Test 3 are scheduled to be released in mid-August. The fourth round of materials testing began on July 31, and four of the five items in Test 4 are similar book materials as were studied in Test 1. However, in Test 1 the items were laid flat and exposed to air, whereas for Test 4 they will be stacked to simulate their common storage configuration in bins, book drops and on shelves. A fifth item, expanded polyethylene foam, was not tested previously and will be added to Test 4 research. Results from this round of testing are expected to be released in mid-September.
