If you are editing core encyclopaedic articles and adding references from newspapers, blogs and other web sources, please stop, you are not helping as we all deserve better quality sources. Here are some places where reliable sources can be found. Remember to try Google scholar as well as web searches with "site:archive.org". Try WP:RX for requesting inaccessible journal papers. WP:RX has some truly unsung heroes of Wikipedia, librarians who make a big difference to parts of the world where the idea of public libraries never took root.
I am happy to help anyone with research content on some areas such as Indian birds and can access nearly all of the Journal of the Bombay Natural History Society issues. I currently have access to some resources on the incredible Wikipedia Library and if you are a regular editor here you too will be able to access some of the resources there. I will be happy to provide content from these sources if I can see that you are working on specific Wikipedia articles.
