An unfortunate intervention of digits remained undetected during all the publication steps of the paper
(A&AS 135, 1999, 467-475) and introduced an erroneous (pre-Colombian!) date in Table 1 for the "range
start" (4th column) of the "total sample Canada + U.S.A." (4th line).
The correct table should read as follows:
Table 1. Samples and properties
(*) All ranges end in 1998, except the "publishers" one where no foundation year more recent than 1995 has been registered.
(**) A value lower than the size of the corresponding sample indicates
that some duplications of entries for the same organizations (at different
locations, but with the same foundation year) have counted only
for one occurrence (see text).
