Cross-campus collaboration for library website design and management can be challenging, but the process can produce stronger, more attractive, and more usable library websites. Collaborative library website design and management can also lead to new avenues for marketing library tools and services; expert consultation for library technology implementation; improved collegiality, respect, and communication between departments; and a richer understanding of patron needs. Recommended best practices for positive and productive cross-campus collaborations include assuming positive intent, thinking holistically, acknowledging and appreciating others' abilities, observing one another at work, and collecting and using data to drive decision making.
