I am building a database from several online sources like Engineering Village. Everyday I am searching different/close/related keywords that pertains to my research topic. Then, I am (everyday) exporting and printing out the documents to do manual filtering depending on the relevance of the article/report. I also importing/appending daily search results into my cumulative list. This may lead to duplication which Reference Managers identifies and filters out in most cases. How do I have a daily reference list such that there is no duplicates? In order words, is there a way to know each time I append my references which are the new ones that I generated (through query) only today.
Please let me know if you need any clarifications. Thank you for your help.
