A Season for Preservation Storage

Students in my Preservation Science and Practice course are finding that their final paper is unusually timely this year.  Their assignment is to write a Request for Proposals (RFP) for a preservation storage facility.  An RFP describes the details of a project for an audience of prospective vendors or contractors.  Here, the students describe their imagined ideal preservation storage space for architecture and engineering firms that might wish to bid on the work.  Students get to show off everything they’ve learned throughout the semester while they practice a skill they’ll need in the field: introducing preservation concepts to a non-specialist audience.

Collections Preservation and Research Facility

High-bay storage at UT’s Collections Preservation and Research Complex is accessed with a cherry-picker when books are requested on campus.

Meanwhile, students don’t need to look far to find two new preservation storage facilities nearby!  UT Libraries has recently completed construction of the Collections Preservation and Research Complex, a cold, high-density storage addition to the previous Library Storage Facilities.  Here, high-bay storage maximizes capacity, while cool and dry conditions maintain preservation standards for various campus materials.

And at the Texas State Library and Archives Commission, ground has been broken for a new State Archival and Records Storage Facility north of Austin.  This facility promises at least 25 years of collections growth capacity, with preservation storage conditions, a conservation lab, and digitization services.

Congratulations to our local institutions for their planning and investment in the future of their collections.  At the iSchool, we’re preparing our students to manage projects like these as they enter their careers.

Let’s Make Some Paper!

This week, students in my course INF 393C Preservation Science and Practice tried their hand at making paper. Paper is made from a vat of macerated cellulose fibers in water.

Our papermaking set-up: the white tubs hold macerated paper fibers in water.

When a thin slurry of fibers is deposited on a screen, the fibers begin to undergo hydrogen bonding. This bonding, along with physical entanglement, is what creates a sheet of paper.

Cellulose molecules are combined to create a sheet of paper. The dotted lines represent hydrogen bonds.

As we learn in class, a great deal of activity can occur over time at these hydrogen bonding sites. Hydrogen bonds are weak bonds, and they’re prone to break in the presence of pollutants, atmospheric moisture, light, and other agents. When they break, the cellulose strands shorten, and the paper gradually becomes fragile and brittle. Through the preservation measures studied in class, we aim to slow down this process and prolong the lifetime of cultural materials.
