Data sources
Where the venue index gets its numbers and dates, and how we choose what to list.
Citation measures
Journal metrics (h-index, two-year mean citedness, works per year, citations, open-access status, listed publication charges) come from OpenAlex, an open index of scholarly works released under CC0. Because OpenAlex indexes different journals and document types from Scopus or Web of Science, its values differ from theirs: compare a journal's measures only with other measures from the same source. For each field we list the 50 journals with the highest h-index whose topics fall mostly in that field and that are still publishing; multidisciplinary journals such as Nature or Science sit in no single field and are not listed yet.
Deadlines
Computer-science deadlines, editions and past deadlines come from ccf-deadlines, a community-maintained list, checked against official sites where we write a guide. Deadlines in other fields are facts taken from each organiser's public announcement and linked to it; where the next call is not out yet, the page says so and gives last year's date as an estimate. Dates change: always confirm on the official site before you submit.
Rankings
Official rankings (CORE, CCF, SCImago quartiles, national lists) are not reproduced; each venue page links to them, and how venues are ranked explains what they mean.
