  We have carried out a search for new R Coronae Borealis (RCB) variables using
the publicly accessible data from various photometric sky surveys and-whenever
available-AAVSO visual data. Candidates were selected from Tisserand`s
"Catalogue enriched with R CrB stars" and by a visual inspection of light
curves from the ASAS-3, MACHO, NSVS and OGLE surveys. We have identified two
new RCB stars, four RCB candidates, and one DY Persei (DYPer) star candidate.
Our identification was based mainly on photometric variability, color-color
diagrams, and further information drawn from various catalogue sources;
spectroscopic classifications were also reported in our analysis whenever
available. Additionally, we present a sample of interesting stars
which-although showing similar photometric variability-can be ruled out as RCB
and DYPer stars or have been rejected as such on spectroscopic grounds in
recent studies. Although not useful in the investigation of the aforementioned
groups of variables, these objects defy an easy classification and might be
interesting targets for follow-up studies which we encourage for all stars
presented in this paper.
