%Dear Sander, you may try the attached revision of your bst file. I
%have made only small changes:
%
%
%   * Inserting an "emphasize" into the original format.bvolume function
%     -that's for italicizing the volume word and number.
%   * Changing the bbl.of into a ". " (note the space after the period) and
%   * Removing the "space.word" commands wherever they follow an "bbl.of".
%
%
%The latter two points remove the extra space between volume number
%and period. Explanation of this: Normally bbl.of is a word and
%should be surrounded by spaces (that's why they call that function
%there originally). If we redefine it to a period, it should not be
%preceded by a space but should nevertheless be followed by one.
%This is now the "manual" solution. The more elaborated solution
%would have been to change space.word in order to work similarly to
%the tie.or.space.prefix, i.e. here to insert the space preceding
%the word only if the word has a length of more than one
%character(s).
%
%
%The problem here is that bibtex styles generally are not prepared
%for having multi-volume books within a series. I tried your bst
%file with a citation of a paper in volume 2 of a book which (all
%two volumes together) is number 55 in some series. Actually, you
%cannot specify both numbers. And if you specify volume and series,
%bibtex apparently assumes that volume specifies the number within
%the series.
%
%
%You should be careful if you have also the other type of
%citations, i.e. single-volume books which have some number in a
%series.
%
%
%Regards,
% Cord
%
%
%PS: I have learned one thing for myself: makebst-generated bst
%files are even more difficult to read/understand/change than
%normal ones

 % This bibliography style file is intended for texts in ENGLISH
 % This is an author-year citation style bibliography. As such, it is
 % non-standard LaTeX, and requires a special package file to function properly.
 % Such a package is    natbib.sty   by Patrick W. Daly
 % The form of the \bibitem entries is
 %   \bibitem[Jones et al.(1990)]{key}...
 %   \bibitem[Jones et al.(1990)Jones, Baker, and Smith]{key}...
 % The essential feature is that the label (the part in brackets) consists
 % of the author names, as they should appear in the citation, with the year
 % in parentheses following. There must be no space before the opening
 % parenthesis!
 % With natbib v5.3, a full list of authors may also follow the year.
 % In natbib.sty, it is possible to define the type of enclosures that is
 % really wanted (brackets or parentheses), but in either case, there must
 % be parentheses in the label.
 % The \cite command functions as follows:
 %   \citet{key} ==>>                Jones et al. (1990)
 %   \citet*{key} ==>>               Jones, Baker, and Smith (1990)
 %   \citep{key} ==>>                (Jones et al., 1990)
 %   \citep*{key} ==>>               (Jones, Baker, and Smith, 1990)
 %   \citep[chap. 2]{key} ==>>       (Jones et al., 1990, chap. 2)
 %   \citep[e.g.][]{key} ==>>        (e.g. Jones et al., 1990)
 %   \citep[e.g.][p. 32]{key} ==>>   (e.g. Jones et al., p. 32)
 %   \citeauthor{key} ==>>           Jones et al.
 %   \citeauthor*{key} ==>>          Jones, Baker, and Smith
 %   \citeyear{key} ==>>             1990
