Contact

Callista is run by one person, so email is the whole support channel — and it is answered.

Requesting access

Callista is invitation-only and granted per email address. If you would like access, write with:

• the email address you want it granted to — this is the one you will sign in with, so pick the mailbox you actually read
• your name and affiliation
• roughly what you want to use it for

Request access by email.

Reporting a problem

Useful things to include, in rough order of how much they help:

• the question you asked, as you typed it
• what came back, and what you expected instead
• the publication you were looking for, if you know it exists
• the address you signed in with, if it is a sign-in problem

Searches that return nothing are logged and reviewed, so a question the library should have answered and did not is worth reporting even if you found it another way.

Report a problem.

About the publications

Questions about the publications themselves — rights, reuse, ordering, or anything editorial — go to WIFU, not to us. Callista indexes their library; it does not speak for it.
