The library has 10 hours of regular staffing per week. Staffed hours are posted next to the door of the library and on the library webpage: ( To schedule an appointment with the librarian outside of staffed hours, email

While materials may not leave the Hasler Lab building, they should be checked out while in use. To check out materials when the librarian is not present, use the self-checkout computer station OR email with the book title and a picture of the book’s sticker barcode. To return items, place them in the return basket on the librarian’s desk to ensure they are checked in and re-shelved properly.


The library is open during station hours (8:00-5:00). The Trout Lake Station library does not have any on-site library staff. Email Amber Mrnak and for assistance.

Materials may not leave the station but may be taken to the cabins if you are staying on station.  Materials should be signed out on the yellow pad in the library and returned to the shelves when finished.
