<etal> Et Al.
Indicator of the presence of unnamed contributors. Typically indicated in print with
the text “et al.” or with an ellipsis.
Usage/Remarks
EMPTY
Many tag sets model the <etal> element as EMPTY, that is, the element
has no content. Such an empty element is typically used as a placeholder, for example,
to
generate the text “et al.” via a stylesheet. In this Tag Set, the element
is typically used as an empty element, but the Tag Set also accommodates those tag
sets
that expect content inside <etal>, so the
element is modeled with text content instead of as formally EMPTY and may
contain text such as “Associates, co-workers, and colleagues”.
In Citations
The sixth edition of the APA Style Guide used “et al.” in a
different way within a long list of authors. When there are more than 8 authors, the
citation is
expected to display the first 6 authors, then an ellipsis or the words “et
al.”, followed by the last author, as shown in the following citation:
Chen P, Halo W, Rife L, Wang XP, Shen D, Chen J, et al., Fong HK (2001) A photic visual cycle of rhodopsin regeneration is dependent on Rgr. Nat Genet 3:256-260.
This may be tagged in several ways, depending on the publisher’s processing needs:
- Only the authors to be printed or displayed may be tagged, with the element
<etal> as an empty element, used to
generated the text “et al.”:
<person-group> <name><surname>Chen</surname><given-names>P</given-names></name> <name><surname>Halo</surname><given-names>W</given-names></name> <name><surname>Rife</surname><given-names>L</given-names></name> <name><surname>Wang</surname><given-names>XP</given-names></name> <name><surname>Shen</surname><given-names>D</given-names></name> <name><surname>Chen</surname><given-names>J</given-names></name> <etal/> <name><surname>Fong</surname><given-names>HK</given-names></name> </person-group>
- Only the authors to be displayed may be tagged, with the element <etal> containing the interposing text, such as ellipses
(… or …) or “et al.”:
<person-group> <name><surname>Chen</surname><given-names>P</given-names></name> <name><surname>Halo</surname><given-names>W</given-names></name> <name><surname>Rife</surname><given-names>L</given-names></name> <name><surname>Wang</surname><given-names>XP</given-names></name> <name><surname>Shen</surname><given-names>D</given-names></name> <name><surname>Chen</surname><given-names>J</given-names></name> <etal>…</etal> <name><surname>Fong</surname><given-names>HK</given-names></name> </person-group>
- All the authors may be tagged, with the element <etal> used to the hold the text, such as ellipses or “et
al.”. The authors that are to be displayed
may be flagged with a @specific-use
value such as “display” or the authors that are not to be displayed may be flagged with a @specific-use such as “not for display”
or “search-only”:
<person-group> <name><surname>Chen</surname><given-names>P</given-names></name> <name><surname>Halo</surname><given-names>W</given-names></name> <name><surname>Rife</surname><given-names>L</given-names></name> <name><surname>Wang</surname><given-names>XP</given-names></name> <name><surname>Shen</surname><given-names>D</given-names></name> <name><surname>Chen</surname><given-names>J</given-names></name> <etal>et al.</etal> <name><surname>Fong</surname><given-names>HK</given-names></name> <name specific-use="search-only"> <surname>Cho</surname><given-names>S</given-names></name> <name specific-use="search-only"> <surname>Ping</surname><given-names>M</given-names></name> <name specific-use="search-only"> <surname>Wang</surname><given-names>CJ</given-names></name> </person-group>
