How to read these numbers

The reader counts what the printed programs list. It does not count who attended, and it cannot see changes made after the program was printed.

What is counted

A listing is one person in one role in one session.
People are names joined on an exact match. The Computers and Writing corpus has had no reviewed merges, so one person printed with two spellings counts twice.
An institution is matched when the printed affiliation is identical to one the CCCC or IWAC reader already matched. The share outside the US uses only matched institutions.
A person page exists only for people listed at two or more conferences. The 1985, 1997, 2007, 2008 and 2012 programs do not count toward that, because they are OCR'd scans with heavy recognition noise.

Where the series break

1987 and 1988: no program in the corpus
1991 to 1994: no program in the corpus
2016 and 2017: programs are at the WAC Clearinghouse, not in this corpus
2020 and 2021: no program in the corpus
2007 and 2008: OCR of scanned programs, low confidence
2018 and 2019: the programs print names without institutions
2022: the program prints names without institutions
2024: the schedule names no one for its concurrent sessions, only the opening town hall and the keynotes

How each year was read

1984: The first Computers and Writing conference. Read from a scan; the program prints no chairs.
1985: Read from a badly degraded scan. Some affiliations are only a city, because that is all the program prints.
1986: Read from a scan. Session 13 is missing from the capture, and the program prints equipment codes where later programs print rooms.
1989: Read from a scan. The D time slot prints no time, and the keynote and optional talks were assembled by hand.
1990: Read from a scan; keynotes were assembled by hand.
1995: Read from a scan. Codes in several slots are assigned by order within the slot, because the program prints the labels in a block before the sessions. A few person and title pairings are off where columns interleaved.
1996: Read from a scan with damaged session headers, so many codes come from the slot header plus a running count. Workshop W3 is missing.
1997: Read from a very noisy scan. About 20 to 25 sessions are missing or merged, and the program prints no chairs. Treat every row as a draft.
1998: Read from a scan. Sessions C7, F3, G5 and H5 were not captured, and the Town Hall participants print e-mail addresses instead of institutions.
1999: The program prints no institutions for session participants, so almost every listing here has none.
2000: Read from a scan. Sessions B7, B8 and the film session are missing from the extracted text.
2001: The program prints names only, with no institutions anywhere.
2002: The program prints no institutions for paper presenters; the few institutions here come from workshop facilitator lists. Some workshops list coordinators but no presenters.
2003: Most panels print no moderator.
2005: About a tenth of the listings print no institution, and many panels are marked self-moderated.
2006: The program prints names only, with no institutions.
2007: Read from an OCR'd scan. Names and institutions carry recognition errors, and the authors of a paper are split by a rule of thumb.
2008: Read from an OCR'd scan. About a quarter of the listings print no institution, and OCR damage to session codes was repaired by running order.
2009: The Thursday workshops (about eight to ten sessions) are not included.
2010: The Thursday workshops and two featured sessions are not included. Poster presentations are one merged session.
2011: The program prints no chairs, only discussion leaders and town-hall moderators.
2012: Read from an OCR'd scan with letter errors in names, titles and rooms. The program prints no session codes, so the codes here (A-01, TH-I and so on) are local identifiers, not citations.
2013: The program prints no session types, and prints a chair as a bare name.
2014: Paper titles and presenter lines are separate lists, so a few sessions have no paper-to-person pairing. The Thursday workshops are not included.
2018: The program prints names only, with no institutions. Poster presentations are one merged session.
2019: The program prints names only, with no institutions and no chairs. Poster presentations are one merged session.
2022: This program came from the conference organizers, not the Digital Press book. It prints names only, with no institutions and no chairs, so every listing here has no institution. The keynote's institution appears only in his biography and is not taken from it.
2023: This program came from the conference organizers, not the Digital Press book. It prints no chairs, and the program prints no city or host institution. Session codes A.07, E.05, F.04, G.01, H.04, AS.21 and AS.23 are not printed. Asynchronous sessions have no time or room.
2024: This schedule came from the conference organizers, not the Digital Press book. It lists each session's time, room and title but names no presenters for the concurrent sessions, so only the opening town hall panelists and the two keynote speakers appear as people. The schedule prints no session codes, so the codes here (A-01 and so on) are local identifiers, not citations.

Caveats

This is a draft built from the program PDFs in Are We There Yet? (Marlow and Purdy, Computers and Composition Digital Press) and, for 2022 to 2024, from programs supplied by the conference organizers. The programs print no names for some sessions' participants and no institutions for some years, and a name that carries no institution (2001, 2006, 2018, 2019, 2022) is joined to others only by spelling, so common names may be joined wrongly. Abstracts are in the source programs but are not shown here. Check any figure you plan to publish against the session pages.
