In late June, we released an analysis of many of the results from Nature and Naturejobs's first international salary survey, which received more than 10,500 responses from scientists worldwide (see http://go.nature.com/RVvqWe). It detailed trends related not only to scientists' incomes, but also to their job satisfaction. Accompanying the analysis were expert commentaries (see http://go.nature.com/8Z6tnr) and a podcast sampling some of the survey's more interesting outcomes (see http://go.nature.com/VwUzzp).

This week, we are offering readers an additional online-only resource, free with Naturejobs registration. Our search tool will allow users to probe the data set in even more detail — on their own terms and according to their own interests (see http://go.nature.com/xV3dnZ).

Using the tool is intuitive. Readers first select a topic from the drop-down menu, such as salary, then a filter — such as career stage or satisfaction. The results are instantly available as a graph and a table.

Interested in how much money our biologist respondents make? Choose 'Current salary of primary job', then filter with 'Primary subject/research area' and 'Biology'. The large number of scientists on US$40,000–50,000 reflects in part the large number of postdoc respondents (which, in turn, reflects the large number of postdocs out there).

Want to know how biologists rate the different sources of job satisfaction? Choose 'Sources of job satisfaction' and filter with 'Primary subject/research area' and 'Biology'. Users can generate quite subtle results. Try choosing 'Sources of job satisfaction', then filtering 'Overall job satisfaction' with the subcategory 'Very satisfied'. The results suggest that among those who reported being very satisfied with their current position, 'degree of independence' and 'guidance received from co-workers' were among the leading factors contributing to contentment.

We have chosen to display and make available for selection only categories and subcategories with sample sizes of at least 50. This means that data from many countries — those for which we had small sample sizes — will not be available. And, as explained in our frequently-asked-questions section, there are biases in the data that we have done our best to address (see http://go.nature.com/MP91Ge).

We hope this new tool helps inform, enlighten and even entertain, whether users are browsing the results, using them for a presentation or simply sharing them with colleagues.
