Unsub is a fully open source project from the nonprofit Our Research. To keep our servers humming, we count on support from Librarians Like You, in the form of one-year subscriptions to Unsub.

Our support model is based on the size of your library's current annual budget for materials (print and electronic serials, books, and so forth).

Here are the pricing tiers:

Library materials budget (USD)

Cost (USD)

$0 - 500,000


$500,000 - 1,000,000


$1,000,000 - 1,500,000


$1,500,000 - 2,000,000


$2,000,000 - 2,500,000


$2,500,000 and above


If you're not able to determine your library materials budget, use your best estimate. If you're on the border between two tiers, feel free to pick the lower one.

If your budget isn't in US Dollars, convert it from your local currency into USD and then use the chart above as usual. Some folks like to use the average exchange rate over the last year, while others prefer to use today's rate; either is fine by us.

If you're looking to get a quote for a consortium, rather than a single institution, then please get in touch with us, either by email (team@ourresearch.org) or the blue button at the bottom right of your screen.
