with a consumer/corporate email address (93%), reaffirming the
attractiveness of our service to users who are unaffiliated with an
academic library.
• Subject Areas - Physical Sciences & Engineering was the main
over-arching subject category read by DeepDyve users in 2015,
followed by Social Sciences & Humanities (notably Business
journals), which aligns with the interests of our unaffiliated
audience.

greater discovery beyond the most current articles.

small, it did grow from 6% to 8% year-over-year, once again
