Remove page numbering for BEAMER's bibliography being out of frames

Question

I want a beamer presentation with my bibliography at the end. It should have a two-columns layout and a page number that, preferably, is inexistant (or that follows the page numbering from the last slide before the bibliography, even if a long bibliography is written over several slides).

I can get the bibliography to be written over several slides in the desired layout only if the \bibliography argument is written outside of a \frame (or \begin{frame}) argument.

The problem is that I obtain a bibliography with a page number that is repeated all along the bibliography and is all the same (i.e., is blocked) since the last \frame. I have unsuccessfully tried several commands (e.g., \nopagenumbering or \pagenumbering{gobble} or \pagestyle{empty} or \renewcommand{\thepage}{} ).

Does someone has a solution or an idea ? Many thanks in advance !!

Here is a reproducible example: First the file called "refs.bib":

@article{a,
author = { Anat   Freund   PhD },
title = {Commitment and Job Satisfaction as Predictors of Turnover          Intentions Among Welfare Workers},
journal = {Administration in Social Work},
volume = {29},
number = {2},
pages = {5-21},
year  = {2005},
publisher = {Routledge}


}



@article{b,
author = { Louis A.   Penner  and  Alison R.   Midili  and  Jill       Kegelmeyer },
title = {Beyond Job Attitudes: A Personality and Social Psychology     Perspective on the Causes of Organizational Citizenship Behavior},
journal = {Human Performance},
volume = {10},
number = {2},
pages = {111-131},
year  = {1997},
publisher = {Routledge}

}

@article{c,
title = "The influence of job satisfaction on child welfare worker's desire     to stay: An examination of the interaction effect of self-efficacy and     supportive supervision",
journal = "Children and Youth Services Review",
volume = "32",
number = "4",
pages = "482 - 486",
year = "2010",
issn = "0190-7409",
author = "Szu-Yu Chen and Maria Scannapieco",
keywords = "Child welfare, Worker retention, Job satisfaction, Supervisor's     support, Work related self-efficacy"
}


@article{d,
title = "Job conditions, unmet expectations, and burnout in public child     welfare workers: How different from other social workers?",
journal = "Children and Youth Services Review",
volume = "33",
number = "2",
pages = "358 - 367",
year = "2011",
issn = "0190-7409",
author = "Hansung Kim",
keywords = "Child welfare, Job stress, Depersonalization, Social workers"
}

@article{e,
author = {Petersen, Michael Bang and Sznycer, Daniel and Cosmides, Leda and         Tooby, John},
title = {Who Deserves Help? Evolutionary Psychology, Social Emotions, and       Public Opinion about Welfare},
journal = {Political Psychology}}

Answer 1

The following code should fullfil all your requirements except that it is not two column.

• You don't need \usepackage{color} \usepackage{xcolor} \usepackage{graphics} with beamer

• If your beamer version is reasonable up-to-date, you can use \setbeamertemplate{page number in head/foot}[appendixframenumber] to add the frame numbers to the footline.

• you use a plain frame for your title page, you don't need to manually remove the headline as a plain frame has no headline per default

• never use \sections inside of frames, they should only be used outside

• To split your bibliography frame over multiple slides, you could use the allowframebreaks option. noframenumbering will exclude it frame increasing the framennumber. Alternatively you could use \appendix before this frame.

• to not show any page numbers at all on the bibliography slides, they can be removed with \setbeamertemplate{page number in head/foot}{}

• The syntax \large{Big title} is incorrect, these font size commands are switches and don't take an argument. The correct syntax would be \large Big title, however it would be better to not place formatting instructions in the argument of macros like \title but to set the appropriate beamer font \setbeamerfont{title}{size=\large}

• the line \mode<presentation>{} is superfluous and does nothing

• all the spacing instructions \vspace*{0.6cm} etc. in the preamble don't make sense
